What part of no bills will get on the floor until the tax cut and government funding bills are passed don't Democrats understand? The only bill the Senate acted upon in the lame duck session is the FDA Food Safety Modernization Act - and that's probably because cloture was brought before the Republicans made their priorities known. Those should be the priorities of the American people, too - not, like many of the other bills Democrats want to raise in the lame duck session, goodies for the Democratic base like the DREAM Act.
The only other thing the full Senate has done since coming back is hold a judicial impeachment trial.
Nice try, but there is no excuse for holding everything hostage until their little agenda gets passed. It doesn't make Republicans look noble, it just makes them look like the selfish ideologues they really are, but pretend not to be.
