From a reader:

My son … and I went, for the first time earlier this week, to a book
signing/talk for Zev Chafets new book regarding the relationship between
Jews and evangelicals. The event was sponsored by the Republican Jewish
Coalition, a minority group within a minority group. In fact, we felt
almost subversive for being there, even though I have been a Republican Jew
since, well, since I could think logically. But your writer makes a good
point about the unlikelihood of blacks ever voting Republican in large
numbers, similar to the Jewish experience. I think both my son and I have
concluded that, while not inscribed in Ashkenazi DNA, the tendency to vote
Democratic is somehow psychologically imprinted from birth by Jewish guilt,
desire to assimilate, Franklin Roosevelt, and a basic lack of confidence in
a Jew’s place in contemporary society. Kinda like we Jews are still
looking into the candy shop from the outside, wanting in, and still not
feeling like we are welcome inside, turn our backs on the shopkeeper, who,
let it be known, is happy to welcome us to the Party. I’m sure there are
many blacks who feel the least they can do to maintain their authentic
blackness is vote Democratic. You avoid an awful lot of arguments with
your family if you do.
