He won't answer the question because he is afraid of the answer. Lieberman has nothing to lose, he is in the driver's seat making them squirm. I am sure he is really angry inside over what the rats did to him, they act like he is a Pariah, and the rats know that he could punish them anytime, and they would deserve it. Dodd (who threw his hat in the Presidential ring with bundled money) was the worst betrayer, and even campaigned against him. Many of these illegally bundling Organizations(like Citibank) will be dealing with Dodd in his leadership of the Banking Committee, and it is already raising eyebrows. Lieberman can switch for vengeance (not likely) or because he cares about America and it's ability to win against it's enemies, simply a Patriot with Power. The Rats are probably trying to figure out how to not tick him off anymore than they already have, and I believe they are really scared that he will bolt.
It won't help the GOP a bit if Lieberman were to switch parties (which I don't think he will...he would just become another GOP instead of the hugh prize to be fought over)...
If Joes switches...there are 2-3 GOP that would change the other way...
There was some confusion & horror on dem.circles this week. Matthew Lieberman (son of Lieberman) was spotted in NC when Prez. was there with Rove on some energy related talk. Press frenzy was severe, but no one spooted their meeting & it was later explained that Matthew was on his business mission.
