It's gonna be 3-4 more days yet before we see actual post-debate polls that indicate how much voters are swinging towards Mr. Oz.
My guess is that a good number of "as-yet undecided" independents do.
But there's really not that many of them left.
I would expect very very few of the dem-communist voter bloc to change their votes. It's ideology -- they vote for the dem-com candidate, no matter what.
(and that works the other way around, too)
Mr. Oz may squeak out a victory.
But it's still going to be... close.
