I think Dianne Feinstein should step down; given the bottleneck that her temporary absence from the Senate Judiciary Committee places in the way of Biden's judicial appointments.
I wonder why she wants to cling to the job in light of all the damage this situation could do? A younger Democrat, in that position, would be better for the big picture. Come to think about it, Biden, himself, is also up there in the years, but he still seems to be functioning okay.
Maybe Feinstein wants to remain in office for personal reasons to keep engaged and active. If I were in her shoes, I would rather be an elder statesperson (used to be called "elder states man) than have the responsibility and stress of high office.
An elder statesperson can remain as engaged as they want to be expressing opinions, granting interviews, raising money, writing articles, influencing politics and so forth.
Former Justice Ginsberg should have taken that route also. Maybe Biden should consider that as well, though he seems to be functioning. The ideas and the staff behind public officials is what's most important. Younger people can continue to carry the torch.
My vote is still for Biden if he is the main Democratic candidate as I remind people that it isn't just about one person. Biden has a whole staff behind him that's likely better than what a Trump, or other Republican would assemble. I vote for the issues that Biden is more likely to represent.
