Zell Miller? Evan Baye?(sp?)
Hate to break it to you, but Zell Miller is happily retired in Georgia.
Bayh will not desert. Zell is retired. The Democratic Senator that will break ranks is Lieberman.
The only way a Democrat breaks ranks on a deal breaker issue such as Judges, bolton, or S.S. is if they are ready to cut ties completely with the Party. Because the Party WILL cut ties with them. If any in the Dem Party ever considered it, it would be Leiberman or Nelson.
Leiberman wouldn't become a Rep, but he might go Independent. He IS a Liberal, but he could pull off the switch better than Jeffords ever did by being a crucial swing vote. Nelson would become a Republican to win re-election.
The only one I could see breaking ranks is Ben Nelson--of the three (Miller, Breaux, and he) who voted against the filibusters last year who is still in the Senate. Further, Bush appointed Mike Johanns, who was Nelson's strongest possible opponent, to the cabinet, possibly in exchange for a promise to support his nominees or switch to the party.
Nelson might vote with the GOP if his vote is needed to make the rule change. If he doesn't he would have a hard time winning relection in a very red Nebraska. If Frist has the votes, than Nelson will likely vote no and then vote for all of Bush's judges on the floor.
