nate silver of 538 was VERY accurate in 2008. in the days before the eleciton, he will probably know where each swing state is going to go.
So was RCP. Then, there are Gallup's predictions.
No incumbent under 50% in their poll in mid-September has even been re-elected (Obama was at 47%)
Conversely, no challenger who has hit at least 50% in their poll in mid-October has ever lost (Romney's at 52%, which prompted former Democratic strategist, Bob Beckel, to declare,
"If these numbers are correct, IT'S OVER!!")
Will Obama make history or become another statistic?
Will Romney carry on the tradition or somehow flop at the end?
