Mamdani wants to change the Democratic Party. But can he get his House picks over the finish line in Tuesday’s primary?

Mayor Zohran Mamdani told supporters at a Brooklyn rally with his “mentor,” Vermont Sen. Bernie Sanders, that the Democratic Party “must change,” casting the June 23 congressional primaries as a test of his political clout, the next test of New York’s progressive movement, and a referendum on the direction of the party. 

Speaking to supporters at Kings Theatre on June 18, the democratic socialist mayor urged the crowd to help elect the three progressive congressional candidates he has endorsed: Brad Lander, Claire Valdez, and Darializa Avila Chevalier.
