Unless Romney is breaking 60 in every GOP state, the national polls don't make any sense with all these swing state numbers.
Maybe 70 in any state that President Obama lost by more than 10%. If he is gaining or at least holding his own in some of the states that he lost barely (Arizona, Missouri)... he is probably close to even in Georgia if he is up 5% in Florida and North Carolina.
I don't see how that could happen. Somebody will poll a state in which President Obama did badly -- let us say Alabama -- and we shall see. He's not trending toward 50% in states that he won big.
