New Yorkers are voting Tuesday in primaries that could show how much political influence Mayor Zohran Mamdani has built in his first six months in office and how far the Democratic Party’s progressive wing can push its agenda ahead of the 2028 presidential race.
The democratic socialist mayor has endorsed challengers in three congressional districts, including two running against sitting Democratic members of Congress. The move has energized supporters, irritated party leaders and turned several normally quiet primaries into national storylines. The contests come as Maryland, Utah and South Carolina also hold primaries, offering a broader look at political tensions across the country.
In the 10th District, Mamdani is backing former city comptroller Brad Lander against Rep. Dan Goldman. The two were rivals in last year’s mayoral race, but Lander later became one of Mamdani’s most visible supporters, especially among Jewish voters who helped carry him into office. Their alliance has become a focal point in a district where debates over Israel, housing and economic inequality have reshaped political loyalties. “I like Goldman’s experience, but Lander speaks more to what younger people are worried about,” said one voter outside a Brooklyn polling site.
In northern Manhattan and the Bronx, Mamdani is supporting educator and immigrant rights organizer Darializa Avila Chevalier in her challenge to Rep. Adriano Espaillat. Chevalier has centered her campaign on housing and public education, while Espaillat has emphasized his seniority and ability to deliver federal resources. “We need someone who understands what it’s like to struggle with rent,” said a Washington Heights resident. “But Espaillat has brought money into the district.”
And in the 7th District, where longtime Rep. Nydia Velázquez is retiring, Mamdani is backing Assemblywoman Claire Valdez over Brooklyn Borough President Antonio Reynoso, Velázquez’s preferred successor. The race has become a test of whether progressive organizers can maintain momentum in a district that blends working‑class neighborhoods with rapidly changing areas.
Across the three districts, voters cite rising housing costs, public safety concerns, immigration pressures and the Israel Gaza war as key issues shaping their decisions. Economic inequality a central theme for progressive challengers is also driving turnout among younger voters.
The primaries come as democratic socialists gain ground in several major U.S. cities. Washington, D.C., recently nominated Janeese Lewis George as its likely next mayor, and Los Angeles voters advanced a democratic socialist challenger to face Mayor Karen Bass in November. Analysts say the trend mirrors movements abroad, where younger voters in Europe and Latin America have pushed traditional parties toward more left‑leaning economic policies.
Money has poured into the New York races from across the political spectrum. Progressive groups such as the Working Families Party and Justice Democrats are backing the challengers, while centrist and pro‑Israel organizations, including AIPAC‑aligned committees, are supporting incumbents. Labor unions are split.
Political scientists say the races highlight a growing divide between establishment Democrats and a younger, more ideological left. Some Democrats warn that challenging incumbents could weaken the party ahead of 2028, while progressives argue that competitive primaries strengthen democracy.
Official results will be certified in the coming days. The outcomes will show whether Mamdani’s progressive coalition can expand its influence and how much sway the left will have in shaping the Democratic Party’s agenda. As always, voters should confirm certified results through the New York State Board of Elections.
