Again, people are missing the point of this thread. It isn't "Why are Jews so liberal?" It's "Why are there so few Jewish Republicans in Congress?"
But you've already been answered. Because there aren't many Jewish Republicans to begin with
No but lets' say 10 or 20 or 30% of Jews are GOP minded. Can they not chose good candidates from this pool? It is still a decent number?
Do they not run? Do they do bad in primaries? Do they feel uncomfortable running as GOP?
If GOP is the party protecting Israel & Judaism, they do a little better!
