Dems are great about fighting at the last minute to delay a bill that will pass regardless of their protests. The problem is when they lost the battles months or years ago when they failed to respectfully tell older Dems/liberals to retire from Congress, the WH or even SCOTUS. And when they have a dynamic, younger (relatively) senator like Franken, they oust him when a censure or other penalty would have sufficed.
And the cycle keeps repeating itself. Sotomayor should have stepped down in 2023 or 24. Yes, she's "only" 71 now but we could easily be looking at a long term GOP rule of the Senate if not WH. We may turn around tomorrow and she's 80+. You might think that she just got to the Supreme Court but this year she exceeded the average tenure (15 yrs) of a justice. Just imagine another justice, like Jackson who is 54 instead of 71. Damn, there are 2 justices younger than me now.
