Nuclear Proliferation.

With Catkiller’s nuclear primary gambit waiting in the wings, the GOP and Dems try to rally Republican moderates to their side on the judicial filibuster question. With John McCain (R-AZ) and Lincoln Chafee (R-RI) already against the proposition and Olympia Snowe (R-ME) also doubtful, the swing votes include John Warner (R-VA), Susan Collins (R-ME), Chuck Hagel (R-NE), Gordon Smith (R-OR), and Arlen Specter (R-PA).
