I liked this response from Andrew Sullivan in a recent interview with Tim Russert (along with Christopher Hitchens):

AS: But it's also true that our politics are almost conspiring against all sorts of certain positions. I mean, for me to support the war, I also have to support an administration that has John Ashcroft as Attorney General, or I have to support an administration that would strip me of any rights in my relationship as a gay person. It's a horribly difficult environment to operate in if your position isn't simply a partisan one on either side. And I think that's the really hard task. I mean, a lot of Americans, for example, do want this war to succeed, are critical of the president, but do not trust the Democrats. Now where do they go? (laughs)

TR: If you had a ballot in front of you right now, for president, what would you do?

AS: I'd probably write in McCain-Lieberman.

Heh...good answer. I'd prefer McCain-Biden myself (Lieberman is too damned socially-conservative, and isn't especially articulate either.)

By the way, the whole interview is interesting...have a look.
