Orthodox Jews largely vote for Republicans. A few in New York and perhaps Chicago got bought off, but they will pay for it in November.
Conservative Jews are split but there is a major shift towards conservatism underway as old traditions are being undermined by the Marxist Democrats (and black anti-semitism is rising even in Congress).
Reform Jews. Once they were called Atheists. There are a few honorable ones but they keep their mouths shut for fear of being called McCarthyites and baby-killers.
This Jew: I left the Democrat Party in 1968 when they sold us out in Vietnam. Never came back and never will. To do so would be to betray my friends who died in Nam and Cambodia.
This I will never do.
I agree with your descriptions even with my limited exposure. I made a decision to convert to Judaism in 1992, and long story short, I started by attending services and classes at a Reform temple thinking I would be more accepted. Wrong.
I was hungry for religion and ritual and I discovered sadly there was more left-wing politicking and Republican bashing even during service. I ended up walking out one morning after having had enough, actually sobbing all the way to my car.
That was two months short of my formal conversion and though I followed by attending a Conservative temple I never quite made it official. I do consider myself Jewish in belief however.
To add, I ran into one of the Rabbis from Reform a few months later and she questioned what had happened to me. When I told her I wanted religion and not politics of any kind, btw, not even my brand, she wholeheartedly agreed it had been a problem that had driven many away.
