U.S. Rep. Adriano Espaillat, who leads the Congressional Hispanic Caucus and is in his fifth term, was defeated by Mamdani’s most polarizing pick, Darializa Avila Chevalier, a democratic socialist who once helped organize pro-Palestinian protests at Columbia University.

U.S. Rep. Dan Goldman, a two-term incumbent, was beaten by the Mamdani-backed former city Comptroller Brad Lander, a fixture among New York progressives who has often shown sympathy to the democratic socialist movement. And another Mamdani ally, democratic socialist state Assembly Member Claire Valdez, defeated the handpicked successor of retiring U.S. Rep. Nydia Velazquez.
