Mamdani surge falters as NYC House primaries draw modest turnout

NYC's congressional primaries drew far lower turnout than last year's mayoral election, with no sign of a Mamdani-style surge in contested House races; about 367,000 Democrats had voted by mid-day (roughly 10% of the city's 3.5 million), and experts say turnout in a midterm federal primary is typically lower than marquee elections. Four major Manhattan/Brooklyn races—Espaillat-Chevalier, Nadler's replacement, Lander vs Goldman, and Velázquez's successor—shape the coverage, with Mamdani endorsing Lander but staying neutral on Nadler, while DSA-backed candidates face less intense field operations than in 2025 and younger voters under 30 did not turn out in force.
