.....other factors like last-minute revelations or news events. Or, there is ALWAYS the possibility of ballot-box shenanigans from one side or the other.
So I agree with Steve Deace. If I had to bet, I would put the election VERY SLIGHTLY in Obama's favor, not necessarily in terms of the meaningless popular vote, but in terms of the all-important ELECTORAL vote.
In order to win, Romney would have to hold on to FL, VA, and CO, plus move OH, MI, and possibly WI from "leaning slightly" Obama, to wins. Difficult, but not impossible. But if Romney loses FL and OH, it's difficult to see any way he can win.
