Bottom Line Up Front: I think the President took this debate. By a hair. I would have called a tie, or even a slight win for Romney--if not for the Libya exchange. Romney missed a huge opportunity on this, and he seemed unsure of himself--especially on whether or not the President talked about the attack as a terror attack.
Romney did not back down. He went toe-to-toe. He looked Presidential. But I do not think he won.
The race will tighten. It is coming down to the wire.
