My parents (obm) were both (FDR) Roosevelt Democrats (like most Jews of their generation). My father, however, was militantly against abortion due to something from his childhood.
I became a conservative as a teenager, and never looked back (this was the 1970s, and when I turned 18 and registered Republican, my father turned white as a ghost...you'd think I'd just converted to Christianity, lol!)
Back then, the only Jews who were Republicans, it seemed, were business owners. In fact, in the 70s the only Jewish Republican I knew was my committeeman, who owned an auto body shop. Then I met another, the father of a friend, who owned a dress company. But that was it.
Now, it seems as if ALL the Jews I know are Republicans, both rich and poor!
