Both Brooklyn and Queens have huge Jewish populations. (the district is 40% Jewish). The big diff is that Brooklyn’s Jews are far more observant: Orthodox and Hassidic, whereas Queens’ Jews are more secular.
The difference between Orthodox Jews in Queens vs Brooklyn is that if a Queens rabbi tells his congregants “you should vote for Turner,” his congregants will say “OK maybe I’ll consider what you’re saying but I’ll make my own mind.”
While in Brooklyn the rabbis say “it is an obligation to vote for Turner because it is a big disgrace for the Jewish people if Weprin wins” and everyone follows in droves. It is the mother of GOTV efforts.
