Mamdani says democratic socialism can win anywhere in America

After three Democratic congressional candidates he endorsed won their primaries, Zohran Mamdani used a Sunday interview on ABC News’ This Week to argue that democratic socialism can travel far beyond New York City. “I think a democratic socialist can get elected anywhere across this country for any position,” Mamdani said, casting his political rise as evidence that the label can be more than a New York City phenomenon.

The stakes around that claim are higher because Mamdani’s own ascent has already rewritten city politics. He won the Democratic mayoral primary on June 24, 2025, with 573,169 votes in the final ranked-choice round, then defeated former Gov. Andrew Cuomo and Curtis Sliwa in the general election on November 4, 2025. Mamdani was sworn in as mayor on January 1, 2026, becoming New York City’s first Muslim mayor and first mayor of South Asian descent. The city also describes him as the youngest leader of America’s largest city in more than a century.

His allies’ primary wins gave the message fresh ammunition. Claire Valdez, Darializa Avila Chevalier and Brad Lander were the three House candidates Mamdani backed, and Lander and Avila Chevalier defeated incumbent Democrats. For Mamdani, that is the clearest available evidence that an affordability-first appeal, paired with a democratic socialist brand, can break through inside the party. For skeptics, it is still a limited test, since all three victories came in New York Democratic primaries, not in a broader electorate stretching well beyond the city’s political terrain.

Mamdani has tried to widen the argument by pointing to governing results, not just campaign language. In his first 100 days, the New York City government says his administration secured $1.2 billion for universal child care, $9.3 million in worker and small-business restitution, $34 million on behalf of tenants, and fixed 100,000 potholes. Those numbers matter because they show the coalition he is trying to build around bread-and-butter issues, with child care, rents, wages and basic city maintenance at the center.

The debate inside the party has sharpened as a result. House Minority Leader Hakeem Jeffries has minimized the broader significance of the New York primaries, while Bernie Sanders has praised Mamdani and other newer democratic socialists as proof that the party’s old approach is no longer enough. Mamdani has made the case that it is the affordability message, more than the label itself, that can scale nationally. Whether that holds outside New York will depend on whether candidates can reproduce the same mix of working-class economics, city-level results and coalition discipline in places where the electorate is less forgiving.
