In a field where each candidate claimed progressive bona fides, Rabb tacked furthest to the left. He racked up endorsements from members of the “Squad,” won the backing of the local chapters of the Working Families Party and Democratic Socialists of America and held rallies with Rep. Alexandria Ocasio-Cortez (D-N.Y.) and polarizing left-wing political streamer Hasan Piker.

He pushed his rivals to join him in calling Israel’s war in Gaza a “genocide” and attempted to tie his competitors to the American Israel Public Affairs Committee, which has become a lightning rod in Democratic primaries. AIPAC said it was not involved in the race.
