McCain is really losing it

With today's weirdness about McCain suspending his campaign coming after a string of bad days, I'm getting the feeling that he is crossing some kind of line of craziness, mismanagement and self-destruction. It feels like one thing after another is going wrong. Just now he was supposed to appear on Letterman today, then canceled, telling Dave that he had to go back to DC to deal with the economy. Then:

... in the middle of the taping Dave got word that McCain was, in fact just down the street being interviewed by Katie Couric. Dave even cut over to the live video of the interview, and said, "Hey Senator, can I give you a ride home?"

Earlier in the show, Dave kept saying, "You don't suspend your campaign. This doesn't smell right. This isn't the way a tested hero behaves." And he joked: "I think someone's putting something in his metamucil."

Though he doesn't have nearly the cultural power of Johnny Carson, David Letterman is not just another reporter or anchor. They are supposed to be serious, he isn't. When he gets annoyed, as he seems to be in the quote, I think it signals a shift in the general acceptance of what McCain is doing.

Obama's response, that it's "exactly the time" for a debate, is great.
