So long as Feinstein continues to choose to run, there is little that anyone can do. At least those constituents can see that the republican party is a non-starter as they actively make everything worse for everyone.
Afaik, there is not a single R that would pull a Manchin or Simena and vote against party lines (for more progress at least, many of them will vote against out of spite or to push to make things even worse).
Why was someone over 85 put on multiple committees? It’s not like she’s just now slowing down, she’s lost it completely already, this can’t be a surprise to anyone. The system is so fucked.
