We'll see. Obama didn't impress me in his earliest debates, with his tendency to go on tangents and inability to say things simply. But he's looked better in recent interviews, which is a sign that he's getting better at improvisation and folksy-speak.

I think McCain's aids have to be worried about the 3 official debates coming up in the fall . . . Close-ups on McCain's face, questions that demand the ability to accurately recall loads of information . . . If McCain stumbles and if it is attributed to physical/mental deterioration it could sway a significant portion of undecideds.
