I'm a Bernie fan too, but Diane Feinstein bothered me in multiple ways. She was infirm and senile for years but still chose to run for reelection when she and her staff knew she had multiple health problems. Her aids were telling her how to vote, but the voters didn't elect them, and who knows who's interests they represented. Her stubbornness to not retire was a disservice to Californians. I also have concerns that Mitch McConnell is doing a similar disservice to the state of Kentucky with his health problems due to age.

Bernie still has his mental faculties, and could still inspire, and sway representatives while being out of office. I would listen to him, and think progressive representatives would as well.

Losing Bernie and a bunch of other politicians would open a lot of seats for younger Bernies
