The sheer number of letters by rabbis circulating about Zohran Mamdani’s New York City mayoral campaign is “mind numbing,” a rabbi friend texted me earlier this week. There’s the public letter decrying Mamdani, the Democratic candidate, sponsored by The Jewish Majority, which as of this writing has 1,138 signatures from rabbis, cantors and rabbinical students. But two or three other letters are also making their way through her circles.
