Hasn't Letterman always been an angry leftist? I don't watch him myself, so I don't know.
He didn't show it as obviously if he was. (Seems to me, anyway).
Yes indeed. He has more than once stated his stance on homosexuals, and only plays up to Conservatives when it suits him. He is a fence sitter, playing both fields, but in his heart of hearts, he is as leftist as they come. Funny guy, and a good comedian, but leftist as they can get. Watch any re-run show with Ellen and see what I mean.
This I do know: the week after Ronald Reagan passed away, not a word from Letterman, with the exception of one one-liner to open the show after the applause greeting his entrance on stage: "Did you all come here because you heard I was lying in state?"
I don't mind the gags about Bush's feeble speaking skills (don't pretend you don't notice). Letterman defends himself from charges of partisanship by saying "It's my job to make fun of [the President]," but the digs are often too angry to be humorous.
Does Wilson have an answer to the Greenpeace complaints about yellowcake contaminating certain places in Iraq? Greenpeace has interesting info on the stuff.
