No, you don't. They blow past the filibuster (which they don't even do any more, they "call it" with no actual filibuster every occurring) with the "nuclear option" whenever they want to. Simple majority vote. Filibuster is not in constitution, super majority requirement is a parliamentary rule ONLY, not law... they bypass it all of the time, over 200 "exceptions" the last time I looked. You've been suckered... and that's why they do this. Most are oblivious, just how they like it
