This is one of the best articles that I have read on Jews and leftism (their actual religion).
Read the entire thing. It's a great reference article for those endless questions about why Jews tend to vote the way they do.
"The peculiarities of Jewish history and
culture have combined with the left’s attraction to totalitarianism – left or
right, secular or sacred – that has now been stripped of the veneer of
progressive values. Jewish support for the enemies of Israel represents the
triumph of leftism over Jewishness."
