The interesting thing about NC is how early most of the state votes. If the race closes in the final weeks, it actually raises the possibility that Obama wins NC on account of the early vote while losing other swing states that traditionally lean more to the left.
Is the early vote really that D-leaning in a state like NC? Given that early voting will be overwhelmingly white... Romney should win the white vote in NC handily.
The whites early vote 35% for Obama before Romney wins the debates, as opposed to 25% on the election day, and the blacks show up on the election day to seal the deal even if Obama loses other swing states.
I also wonder if GA would be tied right now.
