"You don't suspend your campaign. This doesn't smell right. This isn't the way a tested hero behaves. I think someone's putting something in his Metamucil. He can't run the campaign because the economy is cratering? Fine, put in your second string quarterback, Sara 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!"
-- David Letterman, talking about John McCain
From Deus Ex Malcontent
UPDATE: Cancelling on Letterman is a bad idea... I'm sure McCain is regretting that after last night's show.
