Brad Lander secured the Democratic nomination for New York’s 10th Congressional District after defeating incumbent Dan Goldman by a wide margin in the June 2026 primary, a result driven by differences over U.S. policy toward Israel and strong progressive endorsements including from Mayor Zohran Mamdani. The district, covering Lower Manhattan and parts of Brooklyn, has long favored Democratic candidates in general elections, producing consistent double-digit margins aligned with its voter composition and historical patterns. Jennifer Moore, the Republican nominee, faces structural barriers in this solidly Democratic seat with limited name recognition or campaign infrastructure. Trader consensus at 97% for Lander reflects these fundamentals, though late-breaking scandals, major national political shifts, or unusually low Democratic turnout could still alter the outcome before November 3.
