Brad Lander holds a commanding lead in the June 23 Democratic primary for New York’s 10th Congressional District, reflecting consistent polling margins of over 30 points and strong support in this progressive-leaning area covering parts of Lower Manhattan and Brooklyn. Recent surveys, including an Emerson College poll from May, showed Lander at 57 percent to incumbent Dan Goldman’s 23 percent, driven by Lander’s endorsements from Mayor Zohran Mamdani and alignment with local progressive priorities. A June 1 debate highlighted policy differences but did not shift the trajectory. Minor candidates trail far behind, and with the primary approaching, Lander’s established name recognition and voter base in the district limit realistic paths for Goldman or others to close the gap absent major unforeseen developments.
