That's exactly what we were celebrating. There are 51 in the Republican caucus and 49 in the Democrat caucus (although Zell Miller is AWOL on the Dem side).
I'm not ready to give up on Frist yet. And I'm not just saying that because I'm in TN. Bill Frist is a blueblood...he's an exceptionally talented medical doctor by training. Doctors, by nature generally, are not confrontational. He's conservative and I like him, and I think he's been a very good senator. But he doesn't have the history of conservative advocacy like some of the others in the Senate. I hope Rick Santorum is the next Majority Leader, myself.
