Brad Lander secured the Democratic nomination for New York’s 10th Congressional District after defeating two-term incumbent Dan Goldman by a 66-34 percent margin in the June 23, 2026 primary. The solidly Democratic district, covering Lower Manhattan and parts of Brooklyn, has consistently delivered large margins for Democratic candidates in recent cycles. Lander’s victory reflected strong local name recognition from his service as city comptroller, endorsements from Mayor Zohran Mamdani and other progressive figures, and voter priorities on issues including housing, labor, and foreign policy. Republican nominee Jennifer Moore faces a steep structural disadvantage in a district where Democratic registration and historical turnout heavily favor the party nominee. Trader consensus at 97 percent for Lander aligns with nonpartisan race ratings classifying the seat as safe or solid Democratic ahead of the November 3 general election. Late developments such as unusually low turnout, a major scandal, or a national political shift could theoretically alter the outcome, though no such factors have emerged in recent reporting.
