It's possible. I have no faith in the polls, I think there are several reasons in play this year that make them totally unreliable, the two biggest being the turnout model used and the related problem of measuring voter enthusiasm. I have run into exactly one 'Enthusiastic' Obama guy this year, and he was defensive about it and really struck me more as a heritage-Democrat anti-Romney guy (He was also a union guy on disability). I haven't seen all that many bumper stickers for either one, on the Conservative side it's more because people don't want to draw fire and get their car keyed by some welfare leech, on the Dem side I get the feel they're just not all that into him anymore.
