All 3 Mamdani-backed candidates projected to win NY primaries

Published: 2026-06-23 | Source: reporting

Summary

Live-results coverage of the June 23, 2026 New York congressional Democratic primaries. Establishes the full slate structure the wiki previously recorded only as vague “three DSA wins”: Mayor zohran-mamdani endorsed three candidates and all three won — Brad Lander (NY-10) over two-term incumbent Rep. Dan Goldman, Darializa Avila Chevalier (NY-13) over five-term incumbent Rep. Adriano Espaillat, and Claire Valdez (NY-7) for retiring Rep. Nydia Velázquez’s open seat. Two open/other races broke the other way: Micah Lasher won the eight-candidate NY-12 race for Jerry Nadler’s open seat with backing from Nadler, Michael Bloomberg and Gov. Kathy Hochul, and Cait Conley, a former Biden-administration cybersecurity official, won NY-17 to face Republican Rep. Mike Lawler in November.

Key Claims

• Mamdani-endorsed slate: 3 for 3 (NY-7 Valdez, NY-10 Lander, NY-13 Avila Chevalier).
• Two sitting Democratic incumbents defeated: Dan Goldman (NY-10) and Adriano Espaillat (NY-13). NY-7 was an open seat (Velázquez retiring).
• NY-12 (Nadler open seat) went to establishment-backed Micah Lasher out of eight candidates — the counter-datum to a clean “sweep” narrative.
• NY-17: Cait Conley nominated against Rep. Mike Lawler.
• Turnout indicator: 420,527 NYC voter check-ins by 6 p.m. on primary day, Manhattan highest at 149,521.

Direct quotes worth preserving

“It’s not just a question of electing more Democrats, it’s a question of electing better Democrats.” — Mayor Zohran Mamdani, on his slate strategy

Why citable: the compact statement of the DSA-aligned theory of primary intervention — a direct rebuttal to the “don’t primary incumbents in a midterm” establishment position.

Contradictions / Tensions

• Cuts against a maximalist reading of is-the-dsa-taking-over-the-democratic-party: the establishment held NY-12 in a high-spend open-seat race even as it lost two incumbents. Leverage-not-control again.
• Live-blog format: no per-candidate vote totals in the retrieved text. Numbers come from wikipedia-2026-ny7-primary-results and jta-2026-avila-chevalier-defeats-espaillat.

Notes

Turnout figure is a mid-day check-in count, not final turnout — do not present as the race’s turnout.
