McCain To Letterman: "I Screwed Up"

John McCain made a wary return to Letterman last night after weeks of being ridiculed on the show for canceling his last appearance. And man, Letterman really socked it to him, asking tough questions on the Palin selection, on the threats against Obama shouted at McCain rallies, on the ridiculous Bill Ayers thing. And on and on. Letterman should have moderated one of the debates. The below clip from CBS has been heavily edited as has the one on their site. I have no idea why some of the juiciest bits aren't in there.

UPDATE: Yielding to complaints about the edited clip, CBS has pulled it and replaced it with the full 23 minute interview (including an added commercial at the beginning, of course.)
