This is likely going to be unpopular, but McConnell, for all his faults, is one of the last remaining bulwarks of somewhat sane GOP machinery. I don't like the guy, but he's immeasurably better than having a MAGA fuckstick running the Senate caucus.
All that said, when your politician needs to be rebooted in the middle of public appearances, it's time to trade it in for a newer model.
