All three congressional candidates endorsed by New York City Mayor Zohran Mamdani won their House races in New York’s reliably Democratic districts, according to projections by ABC News . Claire Valdez, Darializa Avila Chevalier, and Brad Lander secured victories in their respective races on Election Day.
Election Day triumphs for the two were almost guaranteed after they won their primary elections. Polanco, CBS News reported. Nydia Velázquez announced her retirement.
Two of the winning candidates, Valdez and Avila Chevalier, are members of the Democratic Socialists of America (DSA). They are both consistently blue. Valdez entered the race after Democratic Rep. She defeated Brooklyn Borough President Antonio Reynoso and other Democratic contenders in the primary before securing the seat in the general election. Mamdani also backed former New York City Comptroller Brad Lander of the Democratic Party in his campaign for New York’s 10th Congressional District. Lander challenged Democratic Rep. Dan Goldman in the primary after Mamdani endorsed him over the incumbent. His victory gave Mamdani another ally in Congress as progressive lawmakers seek greater influence within the Democratic Party.
Mamdani’s support for all three candidates was crucial to their main successes, according to political analyst and law professor J.C. “He is developing an entire congressional delegation that answers to him,” Polanco said before the election. Lander defeated Republican Jennifer Moore, according to ABC News projections.
