I don't really know what to think. I've never been as much of an anti-Lieberman basher as most, although his persistent shilling for the Bush administration is supremely aggravating (and the fact that he was responsible for the inept securities laws that gave us Enron is another big strike against him). His justification for the move was also interesting:
"I am very loyal to the Democratic Party, but I have a loyalty higher than that to my party. That is to my state and my country.
Great words, but I'm not sure I really believe Lieberman is being totally honest. He's loyal to himself, not to the "country." Maybe he's loyal to the country in the egomaniacal sense of "the country needs me, whether they want me or now," but I don't know if I want to give brownie points for that.
