I think by asking for this kind of evidence, you’re barking up the wrong tree. What exactly is the question at issue here? It’s not what Lieberman’s objective status on the liberal-conservative scale is.
If what you’re really interested in is the answer to this question:
You’re not going to get the answer by analyzing how conservative Lieberman is compared to other Democrats or to the Senate as a whole. You’re
It’s not an issue of Lieberman being the most conservative Democrat. It’s not about objective words criticizing liberals or fellow Democrats. It’s about Lieberman using his face time in ways that, mostly by implication, make liberals or other Democrats look bad. It’s about one Democrat making it harder for fellow Democrats to pursue their policy goals, most of which he agrees with. It’s about being a media hog in a way that doesn’t help move the ball in the Democrats’ direction.
It’s not only that he, like many other Democratic senators, supported the war initially. It’s his dare-to-be-stupid continued support of the war in the face of debacle. It’s his implication that criticism of the president is disloyal. (December 2005: “It’s time for Democrats who distrust President Bush to acknowledge he’ll be commander in chief for three more years. We undermine the president’s credibility at our nation’s peril.” Also (don’t have the date for it), criticizing Democrats for being “more focused on how President Bush took America into the war in Iraq” than in winning the war.)
When it came time for all men of good conscience to be outraged at our troops’ behaviour at Abu Ghraib, Lieberman took the opportunity to be Rumsfeld’s apologist: “I cannot help but say, however, that those who were responsible for killing 3,000 Americans on September 11th, 2001, never apologized.” He supported Gonzales’s position on torture and unreviewed detentions.
Lieberman voted to confirm Roberts, Gonzales, and that pinnacle of incompetence Condoleeza Rice. He lectured Democrats who voted against Rice in a bizarrely sentimental way while still coming off self-righteous: “In times like these it is important that the world not only knows that this secretary of state has the ear of the president, but that she has – if you will allow me to put it this way – America’s heart.” He voted against the filibuster of Alito. He voted for the Bush energy bill.
After John Murtha (not exactly your father’s left-winger) concludes Iraq is a disaster, Lieberman says everything’s peachy. (“Our Troops Must Stay,” editorial by U.S. Sen. Joseph I. Lieberman (D-Conn.), Nov. 29, 2005.)
When rumours circulated that Lieberman would be the next secretary of defense, Lieberman pointedly failed to say in a clear and unambiguous manner the one thing any conscientious Democrat should have said: “I will never accept a job in the Bush administration.”
And the capper on this is his defying of the Connecticut Democratic party’s will and running against the party’s endorsed candidate.
Personality wise, Lieberman’s a dick and a weasel. He cancelled an appearance at some ethnic-related event and when asked why he said something like – Don’t write about it or if you do say it was my staff’s fault.
