Jews being lefties didn’t suddenly start at all, it is just the way they vote and the causes they lead and support.
After a 150 years or so of voting and political activism, it is OK to start thinking of a liberal voting block, as liberal.

Sure, they are liberal, but the question is “why are they so liberal?” Especially as it seems to be against their traditional religious beliefs and against their own self-interest.
Anyways, I don’t think you can look even at 150 years of voting records to undermine the author’s thesis. Jews were persecuted by Christians long before they ever got the right to vote, so we have no way to really judge if their political leanings were shaped by that by looking at voting records.
