Brad Lander holds a commanding lead in the NY-10 Democratic primary as the June 23 vote nears, driven by consistent polling advantages over incumbent Dan Goldman. An Emerson College survey from mid-May showed Lander ahead 57% to 23%, building on earlier margins and reflecting strong support among younger voters in this progressive-leaning district that favored Zohran Mamdani in the 2025 mayoral primary. Lander's endorsements from figures like Bernie Sanders and his emphasis on economic populism and foreign policy shifts have consolidated trader consensus around his nomination prospects. Minor candidates remain marginal. A late surge by Goldman or unusually low turnout among Lander's base could narrow the gap, though current evidence points to limited room for reversal before primary day.
