The Rasmussen tracking poll -- yes, Rasmussen -- is out and some of its respondents were interviewed after the debate (although there is no indication as to how many).
It's early, and "most" of the interviews were pre-debate. But so far, it shows no bounce for Romney.
Here is Greg Mitchell's take on it:
Don't want to make too much of this but it's interesting: Rasmussen's daily tracking poll, just out, shows Obama maintaining a 2% lead, with no change since yesterday. I would have thought all of the interviews for this would have been pre-debate last night (the calls are made at night) but Rasmussen instead says "most" were. Meaning some were post-debate. Doesn't say how many were post-debate but curious that no Romney bounce at all. He does point out that only 17% said the debates mattered strongly to them.
