On Tuesday night, Mayor Zohran Mamdani faces a critical electoral moment as he endorses three candidates in competitive congressional primaries. Although Mamdani is not on the ballot, his influence is evident in the predictions surrounding former New York City Comptroller Brad Lander, New York State Assemblywoman Claire Valdez, and first-time candidate Darializa Avila Chevalier.
Traders on the prediction market platform Kalshi estimate a 54% chance that Lander and Valdez will win their respective races, while Chevalier is seen as less likely to succeed. Lander, who is challenging incumbent Rep. Dan Goldman, is viewed as having a strong chance of securing the Democratic nomination in NY-10, especially given the criticism Goldman has faced from left-leaning constituents.
Valdez, backed by the Democratic Socialists of America, is also favored with nearly an 80% chance of winning in NY-7, where she aims to replace retiring Rep. Nydia Velázquez. In contrast, Chevalier faces a tougher battle against incumbent Rep. Adriano Espaillat, with traders giving Espaillat a two-in-three chance of winning.
Additionally, in NY-12, where Mamdani has not endorsed a candidate, Micah Lasher is favored to win the Democratic nomination despite significant spending from AI-related super PACs supporting and opposing various candidates.
The outcomes of these primaries could significantly shape the political dynamics in New York City, particularly as they relate to Mamdani's influence and the broader progressive movement within the Democratic Party
