NUCLEAR WATCH The nuclear option's prospects are fluid. But for those keeping score at home, here's our sense of where things stand:

FOR: 45 Republicans.

AGAINST: 44 Democrats, 1 independent and Sen. John McCain (R-Arizona), Sen. Olympia Snowe (R-Maine), Sen. Lincoln Chafee (R-Rhode Island).

UNDECIDED: Sen. Lisa Murkowski (R-Alaska), Sen. John Sununu (R-New Hampshire) Sen. Arlen Specter (R-Pennsylvania), Sen. John Warner (R-Virginia), Sen. Susan Collins (R-Maine), Sen. Mike DeWine (R-Ohio)., Sen. Pat Roberts ( R-Kansas).

And here's a column posted over at The American Prospect making the case that Sen. John Warner (R-VA) is the key swing vote.
