There's a lot of pressure on Dems to vote No. Ed Whelan (NRO, Bench Memos) says that Kohl is giving similar signs of being pressured into a No vote in Committee.
The DEMs will pull every unethical stunt in the book to stall the inevitable. The committee vote will be party line. I think the committee rules are such that given unanimous opposition from one party, one DEM in the opposition can demand (and get) a one week delay in committee vote on the nomination. But if one DEM agrees to vote on the nomination, then the committee vote is held.
Either way, once out of committee, the debate on the floor of the Senate will be fully partisan by the usual suspects (Kennedy, Boxer, Reid, Durbin, Kerry, et al).
I haven't given any thought into whether any (or which) of the DEM committee members might be swayed to approve of the nominee, or agree to the chair's timing on taking the vote.
