Whoa!
Ok, here's a useful last minute warning.
You know, when I looked at new polls coming in, I always responded - I thought - pretty sceptically.
McCaskill led by 1%? Meaningless, could go either way.
Webb led by 2%? Well, thats nice. But I still dont actually expect him to win.
Tester's lead is down to 3%? Hmm.. so the Dems do still have a good chance... probably that race will go down to the wire...
Menendez is up by 4,5%? OK, he should be safe, I dont need to worry about that one.
Right?
Wrong.
Here's a sobering historical poll analysis by Charles Franklin at pollster.com for you:
From Poll Margin to Wins: Polls as Predictors
He took all eve-of-election statewide polls for Senate, Governor and President races in 2000 and 2002. And he calculated - for example, he took all polls that had the Dem leading by 5%, and then looked at how many of these races were actually won by a Dem.
And yes, it has a pretty, if at first sight bewildering graph to go with it.
But here's a finding for you:
Quote:By the time we see a 10 point lead in the poll for the Dem, about 90% of the Dems [also actually] win. When we see a 10 point margin for the Rep, about 90% of Reps win. [This] means that polls rarely miss the winner with a 10 point lead, but they DO miss it 10% of the time.
And:
Quote:A 5 point lead, on the other hand, turns out to be right only about 60-65% of the time. [..] And for 1 or 2 point leads (as in some of our closer races tomorrow) the polls are only barely better than 50% right in picking the winner.
So. Expect some whom you thought safe, with 5+% leads in the last poll out, to fail regardless. On either side.
Expect some surprises ;-)
