Whatever is happening is moving at a glacial pace.
As bad as Cantor was on policies, he was a good role model for Jewish Republications. If voter segments don’t see any of their kind among a party’s elected officials, they assume the party is not interested in them. If we insist on a party free of Specters and Javitses, then we can also expect a smaller segment of Jewish votes and funding (to say nothing of competing in Northeastern or West Coast states.).
