Definitely half the Senate; they've been there the longest, and seem more interested in internal party structures and hierarchies than governing. Some of them seem genuinely shook by the way Trump has upended Democratic norms, but even then they seem like they just want to get back to business as usual.

The good news is that I don't think the current leadership is long for power. Schumer came across like such a weak imbecile in the shutdown negotiations that even centrists want him gone. Jefferies might hold on for another term because he kept the caucus together during the shutdown, but he's heavily tied to AIPAC, and that is now deeply toxic to most Democratic voters.
