Tuesday Is a Test for a Kennedy Scion, the Mayor

Democratic incumbents are facing spirited challenges Tuesday in at least two of New York's congressional primaries, the latest proving ground in the fight by the progressive left against the party establishment, per the AP.

• US Rep. Dan Goldman and US Rep. Adriano Espaillat are both seeking to stave off candidates backed by Mayor Zohran Mamdani, the young democratic socialist who hopes excitement over his election last year will help reshape the city's congressional delegation. Goldman faces former city Comptroller Brad Lander while Espaillat faces another Mamdani pick, Darializa Avila Chevalier, a democratic socialist who once helped organize pro-Palestinian protests at Columbia University.

• Meanwhile, Democrat Jack Schlossberg, the 33-year-old grandson of John F. Kennedy, is hoping to write his own chapter in Camelot lore as he competes in a crowded field for a seat being vacated by US Rep. Jerry Nadler. Mamdani has made no endorsement in that race. The field includes state Assembly members Micah Lasher, a longtime government hand backed by Democratic leaders; and Alex Bores, whose proposals to regulate artificial intelligence have triggered tech industry blowback. Also in the running is George Conway, a former attorney who helped start the anti-Trump group the Lincoln Project.
• Only months into his first term, Mamdani surprised some by aggressively endorsing candidates who are challenging Democrats supported by the party leadership. If his slate is successful, Mamdani—a registered Democrat—could emerge as a democratic socialist kingmaker with newfound support in Congress, though the play could also risk further dividing fellow Democrats and strain his relationships with party leaders.
• Axios frames it as the Mamdani faction vs. the faction of House Minority Leader Hakeem Jeffries, and has details on the races.
