>>Is one of the independent Senators Lieberman?<<

Yes.

>>Has he specifically said he would caucus with the Democrats?<<

Yes.

>>His vote is extremely valuable--<<

Agreed.

>>has he asked anything in return?<<

He wants back in. He is still in Congress largely due to conservative votes so he will have to split on some issues but I'm sure that has been discussed already. He wants back in and the dems would like to take him back in. What drove them apart--Iraq--is kind of a moot point now. The public has spoken on that. So I think he and the dem party are kind of kissing and making up.
