I suspect that among people who are not antisemetic, being Jewish doesn't preclude someone from being considered white. I know some consider being Jewish to be an ethnic or racial identity rather than just a religious identification, but I don't think most people do.
Most people consider it a racial identity I think, it depends on the person. I have some jewish friends that might identify themselves as jewish, and some that might identify as both jewish and white. Seems that in practice its a ratial identity first and a religion second. One friend doesn't follow the religion whatsoever, but has jewish blood so is technically jewish, but still overall identifies as white.
I suspect the party endorsement is strategic; Feinstein has been polling way above de Léon and has stronger endorsements and leads in every demographic group. If the party can shift some of the support to de Léon in the primary (last poll I saw had them at something like 46-17, with de Léon’s 17 still above any Republican) they maximize the chance that even if the Republicans can solidify behind one candidate, Feinstein and de Léon can get the top two spots in the jungle primary and be the two candidates that advance to the general; if that happens, the party can essentially shift general election spending to other races.
OTOH, endorsing Feinstein would reinforce her position, undercut de Léon, and make it more likely that a Republican takes second in the primary, advancing to the general.
You’re right, I’m sure demographics have absolutely nothing to do with it. And this isn’t a trend that’s going to continue. And it’s not one that many progressives, including white progressives, are actively advocating for.
I didn't say it had nothing to do with it, but I wouldn't have been surprised to see Feinstein face a more progressive white dude either. She's far too far to the right to be a reasonable senator for California in the current political environment.
