It takes 42 Dems to beat a filibuster in fact. They shouldn't be easy, and they damned well ought not be trivial. I forget the number, precisely, but in the first year of the Republican minority they had something the neighborhood of 170 bills they "filibustered."

The general idea now is that it takes 60 votes to pass something in the senate. That's a problem, and it needs to be fixed. If the majority has to work to pass bills, fine. The minority sure as hell ought to have to work to kill them.
