New York 2026 Primary Elections Set Stage for House Control Battle

Voters across New York are casting ballots in critical primary elections that could decide which political party controls the U.S. House of Representatives this November. The highly contested intraparty races highlight deep ideological divisions within the state, transforming local contests into a national battleground for congressional power.

The initial major assessment of New York City Mayor Zohran Mamdani’s electoral sway unfolds Tuesday as three congressional candidates backed by his administration navigate competitive primary fields.

Two sitting Democratic congressmen within New York City face aggressive primary challenges from progressive contenders carrying Mamdani’s endorsement. Concurrently, two separate municipal races feature crowded fields competing for the Democratic nomination, including a high-profile member of the Kennedy political dynasty.

The Empire State remains positioned to exert a decisive influence over the ultimate trajectory of the House of Representatives during the upcoming November midterm elections.

To the north of New York City within the Hudson Valley, an expansive roster of Democratic candidates is vying for the opportunity to challenge incumbent Republican U.S. Rep. Mike Lawler.

Meanwhile, inside the sprawling 21st Congressional District—a territory extending from the Catskill Mountains northward to the Canada–United States border—a candidate backed by Donald Trump challenges an assemblyman favored by the state Republican party to replace outgoing Rep. Elise Stefanik.

1 city, 4 high-profile races

Though New York City retains a heavily Democratic voter base, the primary contests expose significant philosophical fractures among the electorate.

Hostos Community College assistant professor Helen Chang noted that New York primaries represent the primary arena of political competition due to their disproportionate impact on general election outcomes.

Upon entering Brooklyn, motorists encounter signage identifying Mamdani as the mayor alongside Antonio Reynoso as the borough president.

Despite sharing billing on municipal signage, the two leaders remain politically opposed in the 7th Congressional District race, where Reynoso is active. New York Attorney General Letitia James stands with Reynoso, whereas Mamdani favors state Assemblywoman Claire Valdez, who runs alongside City Council Member Julie Won.

Within the 10th Congressional District, spanning Manhattan and Brooklyn, Rep. Dan Goldman faces a primary challenge from former comptroller Brad Lander, who carries Mamdani’s backing. In the 13th District, covering portions of Manhattan and the Bronx, the mayor supports community advocate Darializa Avila Chevalier against incumbent Rep. Adriano Espaillat, who is endorsed by House Minority Leader Hakeem Jeffries alongside Goldman.

Mamdani withheld endorsements in Manhattan’s 12th Congressional District, a race heavily impacted by financial outlays from the artificial intelligence sector.

Former New York City Mayor Michael Bloomberg announced his endorsement of state Assemblyman Micah Lasher for the seat. Meanwhile, former House Speaker Nancy Pelosi backs Jack Schlossberg, a grandson of former President John F. Kennedy, in a field that includes George Conway, Nina Schwalbe, and Laura Dunn.

Noteworthy contests to the north

Located in the northern suburban zone, the 17th Congressional District stands as a prominent swing district that serves as the home base for Bill and Hillary Clinton, represented by Lawler since 2023.

A multi-candidate Democratic field aims to reclaim the district, featuring former National Security Council Counterterrorism Director Cait Conley, Rockland County Legislator Beth Davidson, Tarrytown Village Trustee Effie Phillips-Staley, Michael Sacks, and John Cappello.

In the state’s northernmost boundary, Republican primary contender Anthony Constantino has centered his platform on a close alignment with Trump.

Constantino, the chief executive of Sticker Mule who secured Trump’s formal endorsement, previously generated national coverage in 2024 by erecting a large promotional sign for Trump atop his corporate facility.

His primary opponent, state Assemblyman and retired Marine Corps officer Robert Smullen, campaigns with the official backing of the New York Republican State Committee leadership.

Future Outlook

The outcome of the 2026 New York primaries will immediately signal the ideological direction of the state’s congressional delegation ahead of the November midterms. With national parties closely watching swing districts like the 17th and 21st, the results are poised to shape the legislative landscape and dictate the balance of power in Washington for the coming two years.
