On Soz's little politics blog thread, I excerpted at length a portrait of Tom Cole, the chairman of the National Republican Congressional Committee (NRCC), in the NYT Magazine. Long, in-depth article, very much worth the read.

A while ago, Okie posited, several times, in this thread that all this breaking down of the electorate in endless demographic subsections, all this identity politics and group think, was characteristic for the Democratic/liberal mindset. Butrflynet suggested, on that note, that I bring one or two of those excerpts of the Tom Cole portrait here.

Here is Cole drawing some comfort from the ways in which McCain could open up the electoral map:

And here is a description of the near-stupifying level of demographic detail in which the Republican party's strategists are mapping the various races:

To be honest, I would be a lot more reassured if Obama stopped plateuing at just under 50% of the Democratic vote. He's been at 47-48% in the Pollster trendline for almost two months now, since around February 24. He needs to break out of that "almost a majority but not quite" level. Thats why I was encouraged when he finally broke the 50% mark in both daily tracking poll a week ago, but he's dropped below again since..

As for Pennsylvania, the update a week ago was very encouraging indeed. But over the past week, things seem to have stagnated - I wrote a post about that this afternoon in the cafe, will post it up next.

Another flurry of polls has been conducted in Pennsylvania in the first ten days of this month. This was before the latest flap about Obama's remarks about many Pennsylvanians being "bitter". (Compare last week's update HERE.)


Code:
PENNSYLVANIA

(Last poll,
Clinton Obama Clinton lead same pollster)

Zogby/Newsmax 4/9-10 47% 43% + 4
InsiderAdvantage 4/8 48% 38% +10 (+ 2, 4/2)
PPP 4/7-8 46% 43% + 3 (- 2, 3/31-4/1)
Rasmussen 4/7 48% 43% + 5 (+ 5, 3/31)
SurveyUSA 4/5-7 56% 38% +18 (+12, 3/29-31)
ARG 4/5-6 45% 45% ~ 0 (+12, 3/26-27)
Strategic Vision 4/4-6 47% 42% + 5 (+ 8, 3/28-30)
Quinnipiac 4/3-6 50% 44% + 6 (+ 9, 3/24-31)
TIME 4/2-6 49% 41% + 8
Temple 3/27-4/9 47% 41% + 6




The results at first glance seem to be all over the place: from a tie between Hillary and Obama to an imposing 18-point Hillary lead.

But looking more closely, there's a fair bit of consensus. Seven of the ten polls (Zogby, PPP, Rasmussen, Strategic Vision, Quinnipiac, Time and Temple) are within a five-point spread from each other, all pegging the Hillary lead at 3-8 points. The average Hillary lead is 6.5%; the median lead is 5.5%.

There's just three polls that diverge from the consensus. ARG has the race tied, but I think we can safely dismiss ARG's take. And InsiderAdvantage and Survey USA have Hillary's lead at 10% and 18% respectively.

The previous InsiderAdvantage poll, a week earlier, had a Clinton lead of just 3%; compared to that one, Clinton won 3% and Obama lost 4%. Thats all within the margin of error. Not much of an outlier.

Survey USA on the other hand is really off on its own: in three successive polls in a month, it's had Hillary's lead at 19%, 12% and now 18%. It clearly just sees a different picture from the other pollsters. That's a little worrisome, since it famously differed from most other pollsters in California too, and it was right. On the other hand, it dissented on Missouri's numbers as well, and then it was wrong.

Another worrisome indicator seems to be the trend in the results. Mind you, if you take a step back and look at the trend over a somewhat longer period, so you have more of a reliable sample of polls, Obama's fortunes still look good. But in this particular selection of the very latest ten polls, we see a movement toward Hillary of at least 5 points in three polls (InsiderAdvantage, PPP and Survey USA); a slight and statistically meaningless movement toward Obama in two polls (Strategic Vision and Quinnipiac) and no movement at all in another one (Rasmussen); and a significant movement toward Obama in just one poll, and that's ARG's.

On a perhaps reassuring note, two of the three polls showing a movement towards Hillary were the furthest out ahead in moving the race towards Obama in the previous cycle (PPP and InsiderAdvantage), so that could still be pegged as just a correction of earlier exuberance - which again just leaves Survey USA. But at least the trend suggests that Obama's upward curve of catching up with Hillary stalled in early April.

Somewhere else (pollster.com, I guess) I read an analysis of the demographic breakdown of support in some of these latest polls, and it suggested an explanation for how Obama got to play catch up so quickly earlier and may have stalled somewhat now. It showed - but I'm going by heart now - that he managed to gain significant extra numbers of college educated whites, upping his level of support in the state among them to where it has been in other states. But that level's been reached now, and in the meantime his numbers among non-college educated whites never really budged. To close that last 5-6 point gap, he'd need to catch up among those, and that hadnt happened yet (and who knows, may be a little more unlikely still to happen now after that flap).

Actually, it's a little more complicated than that. What's happening right now is that the Gallup and Rasmussen polls are veering apart ever more. They just dont agree.

Gallup has for a full week now seen Obama in a generous lead. On Monday the 7th, it had Obama breaking the 50% barrier, and since then he's been at or above 50% for six days and at 49% on the seventh. Obama's lead over Hillary has been at 7-10% all week. The flap over his remarks has had no effect, at least not yet: today, Obama's lead rose from 7 to 9 points.

Rasmussen had Obama with a double-digit lead over Hillary for two consecutive days for the first time ever on the 7th and 8th. It still polled Obama at 50% on the 9th. But in sharp contrast to Gallup's numbers, Rasmussen has recorded a rapid come-back for Hillary since. Obama's lead dropped to nine, seven, three, two points. And in a possible sign of the impact the flap over Obama's remarks, Rasmussen today has Hillary ahead by one.

Is Obama leading by 9, or trailing by 1? The double-digit difference between the two polls' findings is pretty unusual; it's only happened four times in the last 78 days. So who is right? Well, usually such a large divergence between the two polls all but disappears again in two or at most three days - as the two of them converge to a point roughly halfway. So maybe the safest thing is to assume the truth is in the middle.

Taking the average of the two polls, Obama is down four points in six days, but that still just puts him at 48%, in the top range of his results the last couple of months. Clinton is up 2 or 3 points to 44%, which has been a fairly standard score for her. The undecideds are relatively low at 9%. Obama's lead over Clinton is 4%, which is not great, but still in the better third of his positions since Super Tuesday.

nimh, I admit to becoming more biased against Obama. I have hoped all along he would knock Clinton out of the race, and hopefully into political obscurity. But I think Obama has pretty much milked his celebrity surge for what it is worth. he may have peaked too soon, if you want to look at it in a sports analogy. My personal preference is he beat Clinton and then McCain beats him easily, as I think as people see Obama more and more, his stock will go down. However, if Clinton beats Obama badly in Pennsylvania, it is still up for grabs between the two of them.

I dont think it'll be up for grabs; Obama's lead in delegates is too large. But it would definitely be damaging for his standing, and indirectly for his chances in the general elections ... And yeah, I'm nervous. <nods>

Hey, again: I wont try to convince you.. you've got your right to your opinions. My post above was about something specific. I dont know if you remember, but a month ago or so you went on a bit about how all this demographic microscoping was typically Democratic, and what it said about the liberal mindset. Wait, lemme see if I can find it back...

Yeah, you wrote:

    The results of liberalism is now on display. To see all the graphs and analysis [..] The Democratic Party created this mess of groupees this groupees that [..]
When I pressed you on what you meant, you left little doubt:

    nimh, call it demographics, fine, but I am pointing out that Democrats view people as groups, not individuals. I realize this is done by all politicians, to some extent, however I think what we are seeing here is a revelation of what you end up with when it is taken to the extreme. Obama and Clinton both have designed their reputations to appeal to groups, and this is the result. [..] The result of carrying the groupism to the extreme is not a healthy thing, and hopefully people will wake up to see the Democratic Party for what it is. [..] I am not criticizing you, but simply pointing out that what you are doing is really instructing us to see the pitfalls of groupism in politics these days, and it is a big part of what the Democratic Party has built its constituencies. upon.
OK, now compare again how one of the Republican Party's campaign chiefs talks about the race:

Quote:
"Let's break it down," he said. "Obviously in the Southwest, [McCain's] going to make us much stronger. [..] Frankly, while some people have problems with his stand on immigration, he probably keeps Hispanics in play [..]. He really helps us in the Northeast and upper Midwest [..]. Then, anywhere where there's a veterans population or military bases. [..] That's a huge advantage for us. Florida, big military presence [etc].

OK, that's still pretty run-of-the-mill -- but not much different from what we were doing. And now look at what the Republican campaign gurus are doing on a day-to-day basis:

Quote:

Again, I dont think there's anything wrong with what the Morgans are doing - hell, I'd love to see their stuff! They must be brilliant. But I mean, the extent of demographic analysis they put in, breaking even each individual township down in detail by race, religion and ethnic origin - I mean, that must be about as extreme as it can possibly get! So that makes it pretty clear that what you were putting down as something characteristically Democratic or liberal, is in fact commonplace practice in both parties.

The national, daily tracking polls...

... show little or no impact of, ahem, "bittergate" ( Rolling Eyes ).

Gallup has Obama expanding his lead to 10% today, when the day before yesterday it was 7%. He's had a lead of 7% or more for eight consecutive days now.

Rasmussen, which previously had shown an 11-point Obama lead turn into a 1-point Hillary lead in five days, today has the swingometer going Barack's way again: he's up three points, Clinton is down two, and presto, there you have a 4-point Obama lead again.

The result: on average, Obama enjoys a seven-point lead, and has now been leading Hillary by four points or more for eleven days.

Here's the graph:

State-level polls ...

... however, have more mixed news.

As you may have heard, there's a new ARG poll out for Pennsylvania that magically has an Obama/Hillary tie turning into a twenty-point Hillary lead ... in a week's time.

Considering ARG's reputation and track record, however, you can safely take that with a giant heap of salt.

The Wall Street Journal "numbers guy", Carl Bialik, has what Pollster.com's Mark Blumenthal calls "a nice assessment of the ARG poll" (and when you read those words, feel free to imagine it being said through the gritted teeth of a polling expert's frustration about maverick pollsters spoiling the name of polling). Here's how Bialik summarises it:

Quote:
there are reasons to question ARG polling numbers. In a polling report card of 2008 primary accuracy issued by a rival survey company, ARG ranked in the bottom half of more than three dozen polling firms, among 2008 primaries through late February. It also ranked near the bottom in another ranking of pollster accuracy at fivethirtyeight.com, a Web site that tracks the Electoral College. And, as I wrote last month, the widely tracked polling averages at the political Web site Real Clear Politics don't include ARG numbers, because of concerns about transparency. Like they've been in Pennsylvania, ARG polls also were volatile in previous primaries, notably in Wisconsin, which saw a 16-point swing in just two days.


Bialik's column also has a hint of good news for Obama in an upcoming Quinnipiac poll on Pennsylvania:

Quote:
Other pollsters' numbers disagree with ARG's. Clay Richards, who runs the Quinnipiac University Polling Institute's Pennsylvania poll, said he doesn't expect his poll that will be published Tuesday to show much difference from the last one, which had a Clinton lead of six points. "I don't see that much movement in Pennsylvania myself," Mr. Richards said by phone from Harrisburg on Monday. He declined to comment specifically on his rival's contradictory numbers.

Moreover, even ARG's Dick Bennett doesnt actually see much effect of "bittergate":

Quote:
Both pollsters agreed that Sen. Obama hasn't been hurt much by his remarks about small-town Pennsylvania voters last week. Mr. Bennett said few respondents mentioned them.

Bennett, instead, credits Hillary's sudden gains in his poll to the negative effect of her tax returns dissipating and "Pennsylvania voters' skepticism about the Obama campaign's message":

Quote:

(That strikes me as more pundit-talk than pollster-talk; the kind of talk you can hear from Rasmussen too, but not from the people at, say, Gallup.)

OK, so no need to worry, then?

Not quite. Because there's also a new Survey USA poll out on nearby Indiana. And it has Clinton in a daunting 16-point lead. Clinton is at 55% - up 3 compared to two weeks earlier. Obama is at 39% - down 4.

Previous polls in the past two weeks had shown more modest Hillary leads of 3%, 9% and 9%, so this is not good news.

In any case, Indiana does not seem to be the neutral, "both sides stand an equal chance" kind of state it's been made out to be.

Finally, on a positive note again though, there's also a new PPP poll out from North Carolina. Also conducted during the "bittergate" (ggrrr.. how inane a name) days. And it shows no change at all.

Compared to a week earlier, Clinton is up 1 to 34%, and Obama is stable at 54%. So at most you can say his numbers are levelling off, but if the lead is 19 points I'm sure he doesnt mind.

This really doesn't surprise me at all. Obama has it entirely correct in describing the Clinton forwarding of this "elitism", "condescencion" cliche as a duplication of Republican-style smear and the rightwing press and radio concentration on it over the last few days makes the point rather clearly. As I noted elsewhere here, that's a staple electoral move from the right. But because of Obama's likeability and unsual ability to connect with large sectors of the public, he's far better equipped than Kerry or Gore (or Clinton) to show up the gambit for what it is. The mainstream media's attention to it is equally predictable, but as a matter of how they now function.

Rasmussen Pennsylvania: Clinton leads grows from 5% to 9%

Clinton: 50% (+2)
Obama: 41% (-2)

See here. It suggests there might be some impact of the "bitter" flap -- but the change for both candidates is well within the margin of error, so there may also have been none.

There's some interesting detail in the write-up. On the one hand, the likely Democratic primary voters seem to be breaking down between Clinton and Obama along conservative/liberal lines:

Quote:
Among voters from households where someone owns a gun, Clinton leads by seventeen points. Voters from other households are more evenly divided.

Clinton leads among voters who say faith and religion are Somewhat or Very Important. Obama leads among those who say such topics are Not Very Important or Not at All Important.

Sixty percent (60%) of Likely Democratic Primary voters in Pennsylvania say that it is Very Important for the government to enforce the borders and reduce illegal immigration. Among these voters, Clinton leads by sixteen.


But this is interesting too. In previous primaries, Obama's support was relatively evenly spread across income groups (unlike with education groups), but still tilted to the higher-income groups. More specifically, Obama's tended to run strongest among those who feel confident and hopeful, both about their own circumstances and chances for improving the country. He did weakest among those who were more insecure / fearful. (This correlates somewhat with income/education divides, of course.)

But in this poll, Obama is up two points over Hillary among the 23% of likely "voters who rate their personal finances as poor", by 46% to 44%. Meaning he does five points better among them than in the state overall.

Asked about the "bitterness" flap itself, there's a rather nuanced response. On the one hand:

Quote:
In Pennsylvania, 75% of Likely Primary Voters have heard of the remarks. Thirty-five percent (35%) agree and 51% disagree.

But on the other:

Quote:
Thirty-seven percent (37%) say that the comments reflect an elitist view of small town America. Forty-eight percent (48%) disagree.

And whatever dint the flap made, it hasn't budged Obama's favourability numbers:

Quote:
Clinton is now viewed favorably by 74% of Likely Democratic Primary Voters, Obama by 72%. Those figures are little changed from a week ago.

Consider it solved!

Two days ago I wrote, "usually such a large divergence between the two polls all but disappears again in two or at most three days - as the two of them converge to a point roughly halfway."

Well, that was half right: they did converge within two days. But not halfway. While Gallup has stuck with an Obama lead of 9-11 points, Rasmussen has gone back from a 1 point Hillary lead to a 9 point Obama lead.

In fact, here's a reason to celebrate! Today, the average of the two daily tracking polls has Obama ahead by 10 points exactly. And that's the biggest lead he's ever had on this measure.

The same average has Clinton down at 40.5%; her lowest tally since Jan. 19, when over a quarter of the voters was still undecided or rooting for a third candidate. Obama is up at 50.5%, only the 6th time in 88 days that he broke 50% -- and five of those times have been in the last week and a half.

Has something finally really changed?

Hey, now that's encouraging!

Sure hope it holds/ gets even better...

I'm starting to wonder if "bitter" might be a sort of reverse NH tears. That is, the event itself didn't really change many minds, but (IMO) the coverage of it/ reaction to it got a backlash from voters. ("Reverse" because in this case it would be to Obama's benefit, not Hillary's.)

Hmmmm....

Won't hang my hat on that, but meanwhile, nice to see those polls and thanks for the updated graphs etc., nimh!

"Reaction to it" includes Hillary's reaction, of course, and this analysis by "Advertising Age" is encouraging there:

Quote:
Hillary, you're in a fight for your political life and you're going to feature some whiney-sounding people on the street. "Wanh-wanh-wanh, Barack hurt my feelings!" Just as Americans don't want to be painted as bitter losers, they don't want to be painted as helpless victims. You should have gone with barely-controlled outrage. Next time, maybe let Fox News put together a clip for you. (Man 2 is especially egregious as he seems not so much like a man on the street but a guy given a script--which is fine if the writing (or the acting) were any good. "The good people of Pennsylvania deserve a lot better than what Barack Obama said.")

Wonder how this will all play out at the debate tonight? Rendell is stepping back from it -- does that signal strategy, or is he off-message?

Lots and lots of interesting poll info here:

One of those that I keep selecting more and more to copy and paste until I've selected the whole thing... here's just the beginning:

Quote:
A new Washington Post/ABC poll shows lots of problems for Clinton. "Democrats by a 2-1 margin, 62-31 percent, now see Obama as better able to win in November -- a dramatic turn from February, when Clinton held a scant 5-point edge on this measure, and more so from last fall, when she crushed her opponents on electability. The poll finds other pronounced problems for Clinton. Among all Americans, 58 percent now say she's not honest and not trustworthy, 16 points higher than in a precampaign poll two years ago. Obama beats her head-to-head on this attribute by a 23-point margin. The number of Americans who see Clinton unfavorably overall has risen to a record high in ABC/Post polling, 54 percent -- up 14 points since January. Obama's unfavorable score has reached a new high as well, up 9 points, but to a lower 39 percent."

Obama Support Among "Bitter" Voters Unchanged
No decline in support among low-income, low-education, religious Democrats

Gallup
April 16, 2008

As Barack Obama and Hillary Clinton prepare for Wednesday night's debate in Philadelphia, Gallup's daily tracking indicates that Obama's support has yet to suffer following his widely reported remarks about small-town voters being "bitter." The remarks were first reported on April 11.

http://media.gallup.com/poll/graphs/080416Dems1_jb5v9e2.gif

Obama said in essence that small-town voters are bitter because the government has not been able to help their economic plight. As a result, they "cling" to religion and drift toward narrow issues such as gun rights, and anti-trade or anti-immigration policies, instead of their larger economic interests.

Clinton has criticized Obama's comments on the campaign trail in recent days and is sure to remind Pennsylvania voters of those remarks in the debate Wednesday night.

Clinton and other Obama critics have characterized his remarks as being insensitive to less-well-educated, lower-income, and religious voters. If his comments are to affect any voters, presumably it would be voters in these subgroups. But an in-depth analysis of Gallup Poll Daily tracking data collected both before and after the controversy shows little or no change in support for Obama as the Democratic nominee among these types of Democratic voters.

The analysis is based on tracking data of Democratic voters' nomination preferences immediately before (April 8-10) and immediately after (April 12-14) Obama's remarks became a major campaign issue. Although Gallup's tracking data do not have a variable that identifies small-town residents per se, it can identify a number of groups that have suffered economically and are presumably the types of voters to whom Obama was referring.

Income

Democratic voters at the lower end of the economic spectrum have disproportionately backed Clinton for the nomination, but her standing among these voters has not changed since Obama's remarks. Obama's support among voters making $24,000 or less a year has shown a slight, but not statistically significant, drop of three percentage points in recent days.

http://media.gallup.com/poll/graphs/080416Dems2_j9bb53.gif

Education

Last week, Gallup reported on the "education gap" in voting in the Democratic primary race, with Obama running strongly among those with a college degree or postgraduate education, and Clinton doing better among those with less formal education. Obama's remarks may have offended voters who did not attend college, but if they did, it has not materially affected his support among this group, which dropped just one point since the controversy began. Because Clinton's support among those with a high school education or less also dipped slightly, the relative positioning of the candidates among this group has not changed.

http://media.gallup.com/poll/graphs/080416Dems3_u2h5x9.gif

Financial Concerns

Education and income are essentially surrogates for lower socioeconomic status, and that may not necessarily indicate economic distress. The Gallup tracking poll can help address the issue directly because it asks voters if they worry about money. Though Clinton tends to appeal to voters with less education and income, Obama runs better among Democratic voters who say they are worried about money. That could be because blacks, who overwhelmingly support Obama, are more likely to worry about money.

Obama led by 15 points among Democratic voters who said they were worried about money before his remarks were publicized, and has essentially the same lead (14 points) since then.

http://media.gallup.com/poll/graphs/080416Dems4_z4m1f6gif.gif

Religion

Obama hypothesized that many of the voters he was talking about "cling" to religion because of their frustration with their economic state. But there is no evidence that more religious Democratic voters have shifted their support away from Obama as a result of his statement. Prior to the controversy, 49% of Democrats who say religion is an important part of their lives supported Obama and 42% preferred Clinton. Obama maintains a similar five-point lead among religious Democrats in the more recent data.

http://media.gallup.com/poll/graphs/080416Dems5_u7n1a9.gif

Black Versus White Democrats

The above analysis looks at subgroups among the Democratic electorate as a whole. But since whites are more likely than blacks to live in small towns, Obama probably had white voters in mind when he made his remarks. Polling has established that Obama receives overwhelming support among blacks, so it is possible he has lost support among lower-educated white Democrats in recent days but offset the losses with gains among lower-educated black Democrats, for example. But an analysis of the relationships reported in this review among white Democrats only finds no evidence that whites have reacted to the controversy in a different way than blacks.

Implications

It certainly appears that, as of April 14 interviewing, Obama's remarks have not hurt him -- either among the Democratic electorate as a whole or among the Democratic constituencies Obama was referring to. Wednesday night's debate may shine a spotlight on those comments and make them known to a wider audience, so the possibility remains that Obama has not completely weathered the storm.

Conceivably, Obama could be hurt more in a general-election context, where voters with the characteristics he describes might already have an inkling to vote Republican, and such remarks could nudge them more in that direction. But Gallup's general-election tracking data -- like that for the Democratic nomination -- have so far shown no deterioration in Obama's standing versus presumptive Republican nominee John McCain.

Survey Methods

Results are based on aggregated data from Gallup's daily tracking data, consisting of telephone interviews with 1,210 Democratic voters, aged 18 and older, conducted April 8-10, 2008, and 1,314 Democratic voters, aged 18 and older, conducted April 12-14, 2008. For results based on these samples of Democratic voters, one can say with 95% confidence that the maximum margin of sampling error is ±3 percentage points.

Margins of error for subgroups will be higher.

Interviews are conducted with respondents on land-line telephones (for respondents with a land-line telephone) and cellular phones (for respondents who are cell-phone only). [..]

A day and, eh, a dozen pages ago on the Obama thread, I posted a rundown of the polls that had appeared after the "bitter flap", and the difference -- or rather, lack of difference -- they showed with the numbers from the same pollsters from before.

I added the following N.B.:

N.B. Note of caution to fellow Obama supporters

Notice how Obama's numbers all fall within a fairly narrow range: 37-45% (and if you discount the always dodgy ARG, 40-45%).

Hillary's numbers on the other hand are all over the place: 42-57%.

That's possible because of another correlation: the less undecideds a poll has, the higher Hillary's numbers. Or: the pollsters who push their respondents more for an answer, see the undecideds turn to Hillary.

Also with the Bradley effect in mind (some people wont tell pollsters they are going to vote against the black candidate), take into consideration that most undecideds might turn out to be Hillary voters.

Another way to reduce the noise in Hill's numbers is to discount both the ARG and PPP polls - the two outliers in the sequence. Then Hillary's range is down to a five-point spread too: 49-54%, and Obama's at 40-44%. I.e., a Hillary win by close to 10 points?


Well, today I found a column by Mark Blumenthal, of pollster.com fame, on the National Journal site teasing out these exact patterns, and coming to about the same conclusions - just more tentatively so, and in a much more informed and articulate way. And with a graph Smile

MYSTERY POLLSTER: Follow The Undecided

Mark Blumenthal
Thursday, April 17, 2008

As with several other states in recent months, Pennsylvania's primary race is producing some unusually divergent polling results. In just the last week we have seen surveys showing Hillary Rodham Clinton leading by 20, Barack Obama up by 3 and everything in between. But for all of the variation in both the results and the methodologies used by the pollsters that reported them, one statistic has been relatively constant. As noted two weeks ago by my colleague Amy Walter, Obama's percentage of the vote has been less variable, typically falling somewhere between 40 percent and 45 percent.

The best way to consider a big mass of data, as my first statistics professor used to say, is to draw a picture. So consider the chart below, which plots the results of each Pennsylvania poll fielded since the March 18 speech by Obama on race and the Jeremiah Wright controversy. The darker blue points represent polls fielded all or in part over the last week, since news broke about Obama's controversial remarks at a California fundraising event.

The wide spread in the cloud of points illustrates the key issue, also noted this morning by NBC's Chuck Todd: Obama's range is more consistent (between 37 percent and 45 percent), "while Clinton's number is all over the map" (between 40 percent and 57 percent).

Dots plotted near the lower left corner of the chart have a bigger undecided number, while those closer to the upper right have a smaller number of undecideds. So as the undecided percentage gets lower, Clinton's support gets higher.

It is worth noting that there are many differences in the methods used by the pollsters active in Pennsylvania. Some use live interviewers, others use an automated "interactive voice response" (IVR) method. Some interview for as long as four to five days with repeated attempts to contact unavailable respondents, while others complete as many interviews as they can in one night with no "callbacks." Some sample randomly generated telephone numbers, others sample from lists of registered votes. And of course, the "likely voter" screens vary. As a result of all of these factors, the demographic and geographic compositions of the various poll samples may differ in ways that are not obvious from the horse race results.

But if we can set those concerns aside for a moment, we ought to consider why the "undecided" result varies as much as it does among pollsters, and why Clinton's support in Pennsylvania appears to riseas the undecided percentage falls.

The large variation in undecideds is not unusual. Ultimately, the size of the undecided category can depend on how hard the pollster "pushes" uncertain voters for a decision: Does the question offer respondents "undecided" as an option? Does it include a follow-up probe asking uncertain respondents how they lean? Are interviewers trained to push for a decision -- repeating the candidate choices as necessary -- or do they immediately take "I'm not sure" as an answer? Does the automated question pause a few seconds before offering "undecided" as a choice? All of these mechanics can help push respondents harder for an answer.

And what does it mean that undecided respondents seem to gravitate to one candidate when pushed?

The most likely explanation is that uncertain voters consider Clinton a safer choice and tend to opt for her rather than Obama when pushed. Obama has long been perceived by Democrats as the candidate best able to bring change to Washington, but Democrats also agree that Clinton has more experience. The combination of the Wright and "bitter" controversies surrounding Obama may be giving some voters pause, and the strategy of the Clinton campaign appears directed at maximizing that sense of uncertainty. This pattern creates the possibility that the bulk of the remaining undecided voters may "break" to Clinton between now and primary day.

One complication here is that the most extreme results on the chart above come from just four pollsters: SurveyUSA, which typically reports a very small undecided number and a bigger-than-average Clinton lead; Public Policy Polling, which typically reports a double-digit undecided number and better-than-average results for Obama; and the American Research Group and InsiderAdvantage, which manage to contribute results at both extremes. All except American Research Group use an automated methodology.

Remove those four pollsters from the chart and the "all over the place" spread in the Clinton percentage largely disappears. On the seven remaining polls in which 6 percent to 8 percent are undecided, Clinton leads Obama by an average of 50 percent to 41 percent; on the 10 remaining polls with an undecided of 9 percent to 18 percent, Clinton leads by an average 47 percent to 41 percent. So the wide variation in the Clinton's percentage is probably about more than than just how hard the pollsters push respondents for a choice.

Some may also be tempted to speculate about the so-called Bradley-Wilder effect, in which polls in the 1980s and early 1990s tended to underestimate support for white candidates with black opponents. The theory was that the fear of "social discomfort" made some respondents withhold their true preference if they thought it would create tension in the interview. But the contradictory evidence here is that polls conducted with an IVR methodology -- which has no live interviewer -- are contributing responses at both ends of the chart above.
