One of the ways to figure out who "won" the debate, is to turn the sound off. Part of the way we process our impressions of the candidates is through body language. IN this debate in particular, Obama and McCain telegraph very different things.

Obama is calm, forthright and presidential, while McCain is confident at times, but also fidgety, blinky and peevish. His refusal to make eye contact with Obama seems even stranger, when there's no sound, especially since Obama seems so much more natural by comparison.

While there is other, important criteria, by which to judge a debate, turning off the sound is an interesting way to get at the crux of the candidate's personality.
