As part of John McCain's "I'm Suspending My Campaign for the Good of the Country" head fake, he canceled his scheduled appearance on CBS's "Late Show with David Letterman". This was one more opportunity where his campaign rather badly mangled the suspension of his campaign.
First Letterman mocked McCain throughout the show's taping, saying that the whole thing did not "smell right." Letterman 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." These are the kind of quotes that could stick.
Then in the midst of taping, Letterman 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?"
"He can't run the campaign because the economy is cratering? Fine, put in your second string quarterback, Sarah Palin. Where is she?"
"What are you going to do if you're elected and things get tough? Suspend being president? We've got a guy like that now!"
Letterman is watched by a lot of people. This could be very bad for McCain.
