Overview
- Three candidates endorsed by New York City Mayor Zohran Mamdani won Democratic congressional primaries on June 23, with Brad Lander and Darializa Avila Chevalier unseating incumbents and Claire Valdez winning an open seat.
- Mamdani told ABC News he believes the democratic socialist model can win nationally and defended his slate as focused on affordability, childcare and working-class issues.
- Prominent moderates and party figures have publicly downplayed the chances that the New York result will translate to swing districts and have circulated anti-socialist pledges to rally centrist voters.
- Civil-rights groups and critics, including the ADL, warned that protest slogans and some candidates' past rhetoric on Israel and criminal-justice policy have raised antisemitism concerns that Republicans could use in midterm attacks.
- Low primary turnout and concentrated activist energy helped deliver the upset results, leaving Democrats to weigh immediate political risks for the midterms and longer-term questions about the party’s direction and messaging.
