Lander Wins NY-10 Democratic Primary, Expands Progressive Wing

Brad Lander is projected to defeat incumbent Dan Goldman in New York’s 10th Congressional District Democratic primary, powered by a progressive coalition led by Mayor Zohran Mamdani and endorsements from Bernie Sanders. Lander campaigned to the left of Goldman, advocating Medicare for All, abolishing ICE, housing expansion, and pausing U.S. aid to Israel, framing Goldman as too moderate. The race, in one of the most Jewish districts, also served as a proxy fight over Israel policy and U.S. support, with Goldman backed by House leadership and AIPAC. Lander’s win signals growing momentum for progressive challengers in New York politics.
