Letterman, hero or just a reformed idiot?

A lot of attention has gone to David Letterman taking on Bill O'Reilly on Letterman's show. The initial reaction is, like my reaction to anytime the Republicans are on the defensive, is hurrah. But an
interesting article by Matt Taibi in Rolling Stone does a good job talking about how people like Letterman were once complicit in this disaster by supporting it, and even goes so far as to say that the middle-ground flip floppers who were for the war and then against it show less real conviction than Bush's gang of idiots - they may have fucked up abominably, he suggests, but at least they're sticking to their guns. I'm not sure I agree the Lettermans of the world are worse than the Bushes, but I would agree you can't congratulate people to much for figuring out years after the fact that something was utterly moronic, and saying so when it is politically safe to do so. The Dixie Chicks or Susan Sarandon slamming Bush years ago is a lot more impressive than Letterman doing it now.

On the other hand, it's great to see Republicans on the ropes at last, even if they're being pounded by a bunch of hypocrites.
