Polls that show Obama gaining: ABC, IBD/TIPP, RAND, Rasmussen (swing states), Reuters/Ipsos,
Polls that show Romney gaining: Gallup, PPP, Rasmussen (all states)
Polls that can be methodologically dissembled if someone doesn't like the results: All of them.
So what does all this tell you? That regardless the toplines, no poll is methodologically pure and perfect. And they disagree with each other. A lot. And substantively at times.
Doesn't matter. Things will change (for better or worse) tonight.
