He’s not up for reelection this year, but there is no reason to tolerate him as Majority Leader in 2023, except that he’ll probably win, just because he has seniority and knows how to twist arms.
What’s needed are some young Turks in the Senate and House who will reluctantly vote for the same old, same old, but on condition that they have clout despite their juniority because they’re the future, just like the Squad in the present Congress, except without stupid people, nut cases and brother marriers (especially if the young Turk in question is male). But if the same-olds can be deposed, by all means, have at it. On the other hand, if you want to “kill” the king, you better make sure that you do.
