The Nuclear Option
That said, there's clearly a simple answer to this. Back during the "nuclear option" debate, the Republicans rolled out a method of eliminating the possibility of filibustering judicial nominees. At that time, Democrats should have raised the ante and said they would agree if we could just end all filibusters on everything. Having missed that opportunity then, Democrats would look like huge hypocrites if they did it now, but it's still the right thing to do: the filibuster's always been a bad rule and eliminating it would eliminate decades of further conversations like this about legislative gamesmanship.
