Zohran Mamdani, progressive upstart, defeats Andrew Cuomo in stunning NYC Mayoral primary upset

Queens Assemblymember Zohran Mamdani, a 33‑year‑old democratic socialist and prominent left‑wing organizer, scored a major upset in June 2025 by defeating former New York Governor Andrew Cuomo in the Democratic primary for New York City mayor. Mamdani emerged from a crowded field as the party’s nominee, overcoming Cuomo’s name recognition and establishment backing in a ranked‑choice contest that reshaped the city’s political landscape. The June 24, 2025 Democratic primary featured Mamdani, Cuomo, City Comptroller Brad Lander, and multiple other contenders in a citywide ranked‑choice election. Official results from the New York City Board of Elections show Mamdani winning the final ranked‑choice round with 573,169 votes to Cuomo’s 443,229, a decisive margin that confirmed his dominance once lower‑ranking candidates were eliminated and their votes redistributed. Analysis of the race found that Mamdani built a new, multiracial coalition across lower‑ and middle‑income and gentrifying neighborhoods, while Cuomo drew more heavily from voters overlapping with the coalition that previously elected Mayor Eric Adams. Mamdani’s campaign centered on affordability measures such as free buses and rent freezes, while critics questioned his experience and foreign‑policy positions, especially regarding Israel. This upset set the stage for the November 2025 general election, where Mamdani went on to defeat Republican Curtis Sliwa and independent Cuomo in a high‑turnout race that produced the city’s first mayor to win more than one million votes since 1969. The primary outcome mattered beyond New York City politics: it signaled the strength of progressive and democratic socialist currents inside the Democratic Party, showed the impact of ranked‑choice voting on candidate coalitions, and raised questions about the viability of political comebacks for figures like Cuomo after scandal and resignation.
