None now.
As recently as last year I might have been tempted to say Manchin, Pryor and Tester.
Regardless of what the say in terms of promises to the represent the state and not the party and so forth, when Reid needs them, they are there, every last one of them. If the election is four years away or five years away like with Manchin, or if otherwise a promise of a cabinet post is what will secure their votes. In 2017, lets say Clinton is President and there is a vote on cap and trade, you can bet a cabinet post will be waiting for Manchin if he is the deciding vote so that he can vote for it and not have to face the voters.
Didn't a bunch of them (Pryor, Heitkamp, etc.) just voted against background checks for gun shows?
