Hard to tell if these people will actually be switching to Romney... We will see tonight. But Obama margin will definitely be way down from 2008.
In 2008, it was a pro-Obama frenzy. In 2012? None of that. Not a single pro-Obama sign, button or bumper sticker.
A lot of traditional areas that normally go Dem will be much closer then Obama would like. The enthusiasm is notably absent and they have had to campaign in traditionally safe states late in the game.
