The GOP’s ability to ignore establishment nostrums in the face of defeat is its great electoral strength. Democrats, by contrast, have a congenital tendency to panic. Abandoning health care reform after they’ve already paid whatever political cost that comes from voting for it in both houses would be suicide. Even if Coakley loses, the House could pass the Senate bill as is, avoiding the need to break a filibuster, and tinker with it in a reconciliation bill that can’t be filibustered. The only thing preventing the Democrats from following through would be sheer panic.
