Did Letterman And Schaffer Just Ruin The McCain/Palin Campaign?

I've never seen Dave better, and Paul is THE brilliant foil. Both of them at peak of performance... And then in walks Keith Olbermann, and Dave and Paul keep on rolling. Infuckingcredibly good live humor.
John McCain and Sarah Palin are finished. Somehow, I think that tonight's show just ruined John McCain and Sarah Palin.
It's gotta be over.
