New York's primary night delivered a jolt to the Democratic establishment—and a boost to the city's left flank, the New York Times reports. Brad Lander, a former city comptroller, unseated incumbent Rep. Dan Goldman in a marquee House primary, attacking him from the left and zeroing in on his stance on Israel. In Brooklyn and Queens, state lawmaker Claire Valdez defeated Brooklyn Borough President Antonio Reynoso for the seat being vacated by longtime Rep. Nydia Velázquez. And in upper Manhattan and the Bronx, community organizer Darializa Avila Chevalier beat incumbent Rep. Adriano Espaillat, the AP reports. That means New York City Mayor Zohran Mamdani swept the primaries in which he logged endorsements: The Democratic Socialist backed Lander, Valdez, and Chevalier, using the primaries as a test of his growing influence and broader left-wing project.

Beyond the city, Democrats in the suburbs voted for Army veteran Cait Conley to take on vulnerable Republican Rep. Mike Lawler, while Manhattan's open seat—long held by Rep. Jerrold Nadler—drew a big-money contest featuring a Kennedy grandson and heavy super PAC spending from tech and Michael Bloomberg. The Kennedy scion lost his race, however; Jack Schlossberg ultimately lost the Democratic primary to New York State Assembly Member Micah Lasher, the AP reports. Other states in play Tuesday include South Carolina, Maryland, and Utah, which are also settling key gubernatorial and House primaries.
