Hard to improve on Chris Bodenner's take here. Yes, Obama did, in such a casual, insubstantial way that I buy his defense that that wasn't his main point. But the McCain camp's seizing on this sliver of an opening was impressive, if not too elevating, as a campaign tactic.
So far, my hope for a substantive, elevated debate between Obama and McCain has not exactly been borne out, has it?
