Brad Lander holds a commanding lead in the June 23 Democratic primary for New York’s 10th Congressional District due to a May Emerson poll showing him ahead of incumbent Dan Goldman by 34 points among likely primary voters, with broad support across demographics especially younger voters. Lander’s endorsements from progressive figures including Mayor Zohran Mamdani have bolstered his positioning against Goldman, who receives backing from Governor Kathy Hochul and House Democratic leadership. A recent debate highlighted policy differences on issues such as foreign aid and economic priorities. With the primary approaching and other listed candidates polling at negligible levels, trader consensus reflects Lander’s sustained momentum in this Manhattan and Brooklyn district. A sharp late shift in turnout or endorsements remains a narrow path for challengers.
