Snowe, OK. Collins is a maybe. Arlen wouldn't dare, would he?
I'm not sure who gets to be the 5th one. I bet a number of the squishy middle are fighting over it! Anyway, I think Specter's role will be to bottle up some nominees in Committee. 7 of 12 renominees are still in committee. A behind the scenes action is ALWAYS underway.
-IF- it comes to a stalled vote on the floor of the Senate, I doubt Specter will vote against imposing a simple majority for calling the vote on the nominee presently under consideration.
I guess it depends upon what he finds in Scottish law.
