Both camps are trying to psyche out the other. Romney saying he's going to point out Obama's lies (oh, brother) and the President's team claiming he's "rusty". I think it will be clear O knows the issues and R has nothing but platitudes.

These things are SO scripted, it really hinges on the direction of the questions. Romney's gonna sweat and smirk like Nixon, and that ain't good. TV is not Mittens friend. I can only hope there's gonna be some good "zingers".
I'm hoping he makes Obama a ten thousand dollar bet.

These things really do boil down to charisma. Even if Romney out-maneuvers and "gets" Obama, Obama won't flop sweat. Romney, like ttm2 said, will just smirk blandly. You can't rehearse having a personality.
