My guess is he didn't get anything at all. I also think the debates are, generally speaking, far more hazardous for Kerry than for Bush.
Sure, Kerry knows how to debate. What he doesn't "know" is how to be personable, human. The man is a walking abstraction.
By the time the last debate is over, I think that he'll wish he hadn't had so many opportunities to flaunt his rhetorical skill.
Chimpy will own Mr. Flip-Flop. Count on it.
