June 23 Primary Upsets Redefine New York’s Democratic Delegation
On June 23, three left-leaning candidates backed by New York City Mayor Zohran Mamdani won stunning Democratic primaries, unseating two incumbent House members. Former City Comptroller Brad Lander defeated Rep. Dan Goldman, while doctoral student Darializa Avila Chevalier ousted Rep. Adriano Espaillat, chair of the Congressional Hispanic Caucus. Assemblywoman Claire Valdez captured the seat of retiring Rep. Nydia Velázquez. All three are projected to win in November and join a House Democratic Caucus led by Rep. Hakeem Jeffries of Brooklyn.
Progressive Momentum and Mamdani’s Influence
Mamdani’s endorsements emphasized a break from “corporate Democrats” and opposition to U.S. aid to Israel, positioning the winners as democratic socialists. Their victories signal a shift toward a more progressive tilt within New York’s congressional delegation, aligning with intra-party debates over policy direction.
Key Candidates and Endorsements
- Brad Lander – Former City Comptroller, critic of corporate influence and Israel aid.
- Darializa Avila Chevalier – Doctoral student, democratic socialist, ran on an anti-Israel platform.
- Claire Valdez – Democratic socialist Assemblywoman, won the district of retiring Rep. Velázquez.
- Micah Lasher – State Assemblyman, won the 12th District primary to succeed Rep. Jerry Nadler; received at least $10 million from Bloomberg’s Stand for New York super PAC.
- Cait Conley – Army veteran, Democratic nominee in New York’s 17th District.
- Adrian Boafo – Maryland delegate, backed by Rep. Steny Hoyer’s AMERIPAC and cryptocurrency super PACs.
- Ben McAdams – Utah Rep., won Salt Lake City district created by a court-imposed map.
Numbers and Funding
Bloomberg contributed at least $10 million to support Lasher. Former Rep. David Trone self-funded his Maryland 6th District primary with $25 million, compared with Rep. April McClain Delaney’s $10 million-plus support. Two incumbent House Democrats in New York were defeated, and three new progressive candidates secured nominations.
Implications for the House Democratic Caucus
The influx of Mamdani-backed progressives could reshape the ideological balance of the Democratic caucus ahead of the 2024 general election. With Rep. Jeffries positioned as the likely speaker-candidate, the new members may influence policy priorities and legislative strategy on issues such as foreign aid and corporate regulation.
Official Statements & Responses
Greg Stanton, chair of the NewDem Action Fund, described the victories of Conley, Boafo and McAdams as “the playbook for how Democrats reclaim the House majority.” Lander’s campaign framed the election as a repudiation of establishment-aligned Democrats, emphasizing a platform that challenges corporate influence and U.S. policy toward Israel.
