I think this actually exposes a bit of the underlying toxicity in very very liberal cities like SF area.
I think in these places, part of a winning messaging is talking about how you fill at least one diversity quota whatever that may be. If you're a straight white European male that becomes very difficult, and you tend to sort of be washed away in the background. It's not like the South where oftentimes, at least historically, whites are unwilling to support any black candidate, but it's sort of a subtle thing.
Also if you read newspaper stories from these communities, it often talks about how candidate X a strong voice for the X community, and part of the reason they'll be a strong voice is because they're part of that community.
This would apply for the gay community but I can’t imagine Jewish men are running as part of a disadvantaged minority group are they?
The Jewish communities tend to be pretty concentrated and block vote so they’re a bit of the exception. Same thing in nyc
