I listened as well, and thought McCain clobbered him. Go figure.
I agree McCain nailed him.
I also thought McCain was much better on substance, though he lacked precision in a lot of his answers.
I thought Obama got the edge on style points -- he did sound better than McCain did. My pont is not about who "won," but rather who seemed to be better -- and these days that seems to be a matter of style, not substance.
