Mamdani’s slate swept several New York Democratic congressional primaries. Darializa Avila Chevalier defeated Adriano Espaillat, Brad Lander beat Dan Goldman, and Claire Valdez won the contest to succeed retiring Representative Nydia Velázquez.
The article describes Gaza and affordability as central issues in the slate’s campaign and says House Democratic Leader Hakeem Jeffries campaigned against Mamdani’s candidates. Mamdani celebrated the wins, while Jeffries said a handful of primary results would not reshape House Democrats.
Elsewhere in the state, Micah Lasher won a Democratic primary that included George Conway and Alexander Bores. Republican Anthony Constantino won the primary for the seat being vacated by Representative Elise Stefanik, defeating state Assembly Member Robert Smullen.
