OK, here's my theory: McCain has a scary (and documented) temper issue. I'm thinking that the reason that he won't look at Obama is because he'll lose his shit and do something *really* embarrassing. If he just pretends Obama's not there, he can get through the debate without grinding his teeth into oblivion, or physically lashing out.
You think I'm kidding, I'm totally serious. This is the man who called his wife a [very inappropriate word] to a reporter. This is the man who lost his shit on his own campaign plane with a bunch of reporters because he didn't like their questions. He's unbalanced.
