Every Republican would vote against him save Coburn, DeMint, Inholfe, Cornyn, Shelby, Sessions, Bunning, and Brownback. I'm not even sure if Santorum would follow along.
There would be no need. He wouldn't get more than 10 votes in the Senate.
Hah, I think he'd get more like between 48 and 51. The only Republicans I can think of that would vote against him are Chaffee, Snow, Collins, Specter for sure, maybe McCain, and who else? Just possibly Voinovich or Lugar? Who am I missing that isn't in lockstep obedience to the religious?
