It it were not for Lieberman's vote against impeaching Clinton I would be tempted to think that Senator Lieberman might be the only principled man remaining in the entire Senate.
Maybe he is still growing up, and has learned that principled people can handle the loneliness.
(MWTH thinks to himself: "listen to me. The only Senator I can say one decent thing about is a Democrat")
I'd invite you to look more closely at Senator Coburn of Oklahoma.
