Given that I have read the comments on this thread and have already noted that my precious KC-Lion has been pinged, I’ll answer the question anecdotally.
The elderly Jews I have known over the years including when I was much younger all told me they voted with the Democrats because they thought the Democrats looked out for the “poor” much better than the rich Republicans, like Nelson Rockefeller for example.
Now that I am OLD, almost all of my Jewish friends vote Republican, including my classmates from elementary and high school, with whom I keep in touch.
You said my answer to this thread better than I ever could. :)
Yes, much of it is because the Democrats are "for the workingman".
With President Trump though, I think that connotation might be changing.
Yes, it’s why the all loved and adored Roosevelt, who enslaved them with the standard democrat Lie.
