Mamdani and Sanders push progressive wave in Brooklyn rally ahead of New York primary
Mamdani warned incumbents who treat their seat as a substitute for action, saying they should "watch out"
NEW YORK, United States (MNTV) — With five days remaining before New York’s Democratic primary, Mayor Zohran Mamdani used a large Brooklyn rally to deliver an urgent message to both voters and the national Democratic establishment: the party must change, and quickly.
Speaking at the Kings Theatre, Mamdani warned incumbents who treat their seat as a substitute for action, saying they should “watch out.” He framed the upcoming primaries not merely as local contests but as a test of the Democratic Party’s direction.
“The Democratic Party must change,” Mamdani told supporters.
He argued that the party had too often focused on managing decline rather than delivering concrete results for working people, and that this approach would fail in future presidential battlegrounds if left unchanged. “It starts now. It starts on Tuesday,” he said, suggesting that New York’s outcomes could signal a wider national realignment ahead of the 2028 presidential race.
Mamdani was joined by Senator Bernie Sanders, a leading figure in the party’s progressive wing. Sanders urged supporters to back movement-aligned candidates and argued that voters are increasingly aware of a system shaped in favour of wealthy interests.
The rally highlighted several progressive challengers in closely watched House races: former New York City Comptroller Brad Lander, challenging Representative Dan Goldman; state Assemblymember Claire Valdez, running for the seat being vacated by Representative Nydia Velázquez; and community organiser Darializa Avila Chevalier, seeking to unseat Representative Adriano Espaillat.
Several of these candidates have the backing of the Democratic Socialists of America and progressive organisations aligned with Sanders.
The event also reflected growing attention to outside political influence in New York primaries, including the role of the American Israel Public Affairs Committee — a recurring point of discussion in progressive campaigns. Sanders reiterated his call to restrict the influence of super PACs in elections.
The atmosphere mixed political messaging with local cultural references, including multiple nods to the New York Knicks following their recent championship. Mamdani, wearing a Knicks jersey beneath his suit, told the crowd, “The only hands we can count on are ours,” emphasising grassroots mobilisation.
Recent polling points to competitive races across several districts. Lander appears to hold an advantage over Goldman, while the contest for Velázquez’s seat is closely contested.
The race involving Espaillat remains less publicly polled, though internal surveys reportedly show Avila Chevalier gaining ground. Tensions over foreign policy — particularly around Gaza — have surfaced in several contests, adding another dimension to campaigns already defined by ideological divides within the party.
