Just to pile on further, since I didn't yesterday: the problem with Bill Kristol isn't that he's a conservative. The problem is that he's consistently and unwaveringly wrong.
In a lot of arenas in life, if you're wrong all the time, you are considered a failure. In the media, if you're wrong all the time but really, really proud of your bad ideas, you get high-profile job offers. I'm filing this under "Things that are bad for America", because I don't know what else to say about letting the incomparably incorrect onto the op-ed pages.
Oh, and in case you're wondering what kind of dumb ass old-school liberals are running the Times these days, check out this awesome quote from Times editorial page editor Andy Rosenthal: “The idea that The New York Times is giving voice to a guy who is a serious, respected conservative intellectual — and somehow that’s a bad thing, how intolerant is that?”
Tolerance for the stupid, a cherished value of a certain kind of liberalism. Enjoy your new columnist, guys. He'd prosecute the entire organization if he could, but it's important to show tolerance and practice diversity in hiring privileged white dudes who can't make good decisions. Maybe after he leaves office, George Bush can fill the op-ed void as Kristol's one year contract expires.
