@flargh I'll disagree if it yields nothing beyond the moment and agree if it does not.
Sure it's performative. The entire existence of our political system is performance based.
As for taxpayer's time, I'm old fashioned. I'd rather see the filibuster require senators hold the floor instead of the rules they've evolved into. If you're going to fight for or against something do something beyond filing a slip and heading out to play golf or make fundraising calls.
