Newsom will appoint Lee in a few days...
Probably so. I don't think Feinstein is making it through to the 2024 elections.
Frankly, I don't even think she will make it through another month...
Even if DiFi DOES croak in a month or two, I don't think that Newsom would just give Lee an incumbency advantage going into the primaries.
I'm not sure he would either. But she's the most likely of the three main contenders to get the appointment.
He probably appoints a placeholder who is not planning to run.
I don't think Feinstein will necessarily croak in a month or two. I think she will just be forced into retirement by friends/family. It can't be very easy for her to get up and go into work each day. At a certain point, it might become impossible. And that's not far off.
