So?
Let them filibuster - REALLY filibuster.
Make them stand up there and talk talk talk until they drop. That spectacle will soon turn off the public.
Remember, did Ted Cruz or Rand Paul get any support when they actually filibustered? No, they were ridiculed and slandered.
The problem with the filibuster now is that you only have to say the word and the Republicans cave. You never have to actually stand up there and filibuster.
Make them make fools of themselves and the filibuster threat will fade away real quick.
That should be the ONLY filibuster.
