Well, most importantly it appears that Obama dodged a call from Lieberman to congratulate him on his election victory, and so Lieberman talked to Biden instead.
Not sure if it means anything, but fact that Senators Patrick Leahy and Bernie Sanders have both now publicly come out and said that his chairmanship should be pulled is significant.
Both Klobuchar and Bayh have said that they think that he should be allowed to keep his chairmanship if he apologizes for his behavior, but you will never, ever, see contrition from Joe, so I’m not sure if that means that they are creating an way to support him, or to oppose him.
Dodd, is still working very hard to keep Lieberman in the tent.
