Senator Joe Lieberman (I), Connecticut

Inherent in politics is the fact that someone always loses. Some lose gracefully, some lose poorly, and, as in the case of Joe Lieberman, some lose their minds. Since being defeated by an antiwar candidate in the Democratic primary in 2006, Lieberman (who was subsequently reelected as an Independent) has pursued his campaign of revenge against his former party, thinly disguised as an act of principle, replete with the quavering sanctimony that no country should have to put up with from anyone, much less from this small man.
