Mamdani's Primary Test: Can Mayoral Mandate Reach Congressional Races?

New York Mayor Zohran Mamdani is backing three congressional candidates in the city's June primary, including a direct challenge to incumbent Democrat Adriano Espaillat. The move tests whether his mayoral victory on democratic socialist politics can translate to down-ballot races in districts he doesn't govern. Sanders appeared at a June 19 Brooklyn rally for the slate, lending national credibility to the effort.
