Former New York City Comptroller Brad Lander defeats incumbent Democratic Rep. Dan Goldman in the Democratic primary for New York’s 10th Congressional District, NBC News, CBS News, and other outlets project. The race is described as a test of divisions within the Democratic Party, including disagreements over Israel-related issues, and as a demonstration of influence from New York City politics, with Mayor Zohran Mamdani backing Lander. NBC News and The Hill report that Lander is projected to win decisively, and The Hill cites Decision Desk HQ (DDHQ) figures indicating Goldman trails significantly as results are partially reported. Fox News similarly characterizes Lander’s campaign as backed by progressive figures, including Mamdani. After losing the primary, Goldman’s bid to retain the seat ends with the Democratic nomination going to Lander, who would face the winner of the general election for the U.S. House seat.
