The only way that the Nuclear Option will actually go to a vote is if both sides believe they are going to win. The Dems are better off keeping the filibuster rule in place for at least awhile if it looks like they are going to lose the vote. The Pubbies would be fools to force a vote when they don't have the 50 Senators in their pocket. So if all 100 Senators are willing to tell both sides the truth about how they will vote their won't be any vote.
OTOH, look what happens if only a few and perhaps only one Senator witholds his/her position from one side or anther or from both. For example look what would happen if the Pubbies have 49 votes plus John Warner's vote and Warner has secretly told Frist he will reluctantly go along. The Dems, thinking they have Warner could let the vote proceed and they would lose. Or, Warner could withold the info from Frist, tell the Dems that he will vote with them and then the vote would proceed and the Pubbies would get killed. And if he told nobody then it would be a roll of the dice for both sides. Would Frist fold? Would Reid? Who knows?
The under the table bit is what we don't know. How committed is anyone to how they say they will vote? Hell, if they asked me if I was going to vote for Hillary, I'd say yes just to know that I had "fixed" a poll and that they are not dependable.
Sounds like a job for Phil Hellmuth!
