Why are we lumping Schumer in this? He's in the minority. He has no say. One rules interpretation and whatever filibuster privileges he has go out the window. He can't stop squat.
No, not by the rules, BUT, his big, ugly mug on the nightly tube can sway a LOT of resentment toward POTUS from the rubes that Schumer BS-ed into voting for himself.
Anything to gum up the works is a win in Democrat town.
