One of the big stories coming out last night’s primaries are the wins for House candidates endorsed by New York Mayor Zohran Mamdani. He endorsed three House primary candidates and each won. Those included Brad Lander, who we might call a left-leaning member of the pre-AOC/DSA New York Democratic Party who allied late with Mamdani during the mayoral primary in which he was also a candidate; Claire Valdez, who won an open primary against Brooklyn Borough President Antonio Reynoso; and Darializa Avila Chevalier who defeated Rep. Adriano Espaillat, a five term Dominican-American rep and longtime NYC pol. So two wins against incumbents (Lander over Rep. Dan Goldman and Chevalier over Espaillat) and another against a quasi-incumbent, since Reynoso is the sitting borough president and had the endorsement of Rep. Nydia Velázquez, whose retirement opened up the seat.
