Democrats - South Carolina
Again, this was what the overall polling results have looked like:
But arguably, the really interesting part of this race, however, wasnt how the overall numbers developed, but how the breakdown by race developed.
Barack's and Hillary's ratings among black voters and white voters separately have changed over time much more drastically than their overall standing. There, the short explanation is that overall he has gone down among white voters and up among black voters - but note the qualifiers.
NB: graph now includes the polls that were done in mid-December! (No polls were done over the holiday season.)
Support among African-Americans
Obama came into South Carolina as the "post-racial" candidate, who had proven his cross-racial appeal by his win in Iowa and strong second place in New Hampshire. Hillary Clinton, meanwhile, was very popular among South Carolina blacks, and was supported by most of the local establishment, from local councillors to the reverends in the black churches.
Nevertheless, already back in December Obama was leading her among black voters, getting about half of them while Hillary had a third. As the race proceeded, the contest became increasingly racialised, and the gap between them among black voters grew.
A running average of the last four polls out showed Obama boosted to the high 50s in the days after the Iowa caucuses. Going from there, his share of the black votes gradually increased to the mid 60s in the last few days.
That's an impressive, but fairly incremental change, and the more important thing to note here might be that the differences between individual polls were MUCH larger than this gradual increase over time. Individual polls have had African-American support for Obama at anywhere between 53% and 73% just in the last week alone, showing that the uncertainty is especially big among blacks.
Hillary's support among blacks mirrors Obama's. At one-third last month, it was down to about a quarter in mid-January. In the days around the acidic debate, her running average dropped down further from 22% to 16%, and if you dont count the ARG polls that's where it still is now.
Edwards, meanwhile, who by mid-January was down to a mere 2%
on average among blacks has picked up a modicum of support since , getting 4-9%.
Support among whites
The main story about the development of popular preferences during the campaign among whites has been how
Hillary lost a fairly imposing lead on
Edwards after the debate, and has now ended up polling neck-and-neck with him.
Back in December, Hillary's support among whites in SC was in the low 40s, while Edwards' was in the high 20s. The same proportions were still in place on the very eve of the debate. But in the four days after, Hillary dropped and Edwards rose so that they are now both in the mid/high 30s.
A direct comparison of polls by the same pollster before and after the debate appears to show a substantive boost for Edwaeds. According to Survey USA, he went from 26% to 34% to 38% within a week. According to Mason-Dixon, he went from 28% to 40%. Only PPP has his support rising more modestly from 30% to 34%.
The other big story here is that
Obama, post-racial candidate credentials notwithstanding, did not manage to compete with the two frontrunners except for a few days directly after the Iowa caucuses.
Back in December, his support among whites stood at 14-24%. Directly after his Iowa win, it was boosted to 29-31%, which made him competitive with Edwards and Hillary. But unlike his support among blacks, which kept increasing, his post-Iowa bounce among whites was short-lived. He soon dropped to around 20%, and has remained there since.
With the exception of the Clemson poll with its high number of undecideds and the one Mason-Dixon poll that had him down to 10%, every poll conducted since 10 Jan. for which I could find data for whites had him at 17-24% - and that's 19 different polls.
So here in this Southern state, it seems (awaiting tonight's results) that Obama could not replicate the appeal he exerted on whites in Iowa, New Hampshire and Nevada. And this is mirrored in his apparent failure to attract Independents and cross-over Republicans in this Southern state, where that was his prime strength in Iowa.
Does that suggest that the whole electoral map in this overall region might look very different? Specifically, that down here Obama is basically still reliant on the same alliance between blacks and liberal whites that propelled Jesse Jackson's candidacy, even as he successfully reached (far) beyond that elsewhere?
