Some will, but most won't. In the US, the majority of Jews have always been what we today call leftist. I doubt that will change much even with rise of open antisemitism on the Left.
THe jews youi mention who are die hard eftists? Research shows that they are generally descendents of Bolshevik Jews who immigrated from the Ukraine and from Russia. Stalin starved them to death to rid himself of them. THe Adam Schiffs and Chuck Schumers, the Nadlers, all come from Bolshevik Jews.
I do not think they are even Jews, I call them Vichy Jews who sell out their own people and who do not follow their own God.Their God is the totalitarian state.
A pox on all of them!
Leftist Jews always think the gator will eat them last.
