[I'll just start by saying Obama has a less than 10% chance of taking states like North Dakota, West Virginia, and Georgia.
Watch out for Georgia! Early voting has been going on for over a month (since 9/22) and he is leading among early voters according to the polls. Blacks are 35.5% of the early vote! Georgia is going to be extremely close on November 4th.
Georgia is not going to be "close" by any reasonable definition of the word.
We'll see. Obama is probably leading by a good margin (~5%) among the votes already cast.
