Don't worry, Romney isn't going to win.
His end-game momentum came out too early. Now he has pulled out of a bunch of States and is focusing on the swing states. Unfortunately for him, he has another, what, 16 days of trying to not say something incredibly stupid?
Of the nine swing states, he is going to need to win 6 or 7 of them to win the election.
That simply isn't going to happen.
