The political landscape of New York underwent a significant transformation on June 22, 2026, as New York City Mayor Zohran Mamdani demonstrated his growing influence. His endorsed candidates secured victories in crucial congressional primaries, reshaping the state’s political dynamics.
This year’s primaries were not just about local politics but also had national implications, with several races potentially influencing the control of Congress. From New York to Maryland, Utah, and South Carolina, voters cast their ballots in high-stakes contests.
Mamdani’s Endorsements Prove Pivotal
In New York’s 7th Congressional DistrictClaire Valdez a state Assemblywoman and Mamdani’s pick, emerged victorious over Brooklyn Borough President Antonio Reynoso. This win was part of a larger trend where Mamdani-backed candidates outperformed established incumbents.
Another notable victory was in the 10th District where former city comptroller Brad Lander defeated incumbent Rep. Dan Goldman. Lander, who had previously run against Mamdani in a mayoral campaign, received significant support from the mayor. In the 13th District community advocate Darializa Avila Chevalier upset incumbent Rep. Adriano Espaillat further solidifying Mamdani’s influence.
Upstate New York Sees a Shift
Upstate, businessman Anthony Constantino secured the Republican nomination in the 21st District. Constantino, known for his large “Vote for Trump” sign, received backing from former President Donald Trump. This race highlighted the divisions within New York’s Republican Party, with the state committee chair supporting a different candidate.
Constantino will face dairy farmer Blake Gendebien the projected Democratic nominee, in the November general election. This contest is one of several that could determine the balance of power in Congress.
Key Races Across the Nation
Beyond New York, other states also saw significant primary races. In Maryland, Adrian Boafo won the Democratic nomination to succeed retiring Rep. Steny Hoyer in the state’s 5th District. Boafo, a former aide to Hoyer, received endorsements from prominent figures, including Maryland Gov. Wes Moore and U.S. Sen. Angela Alsobrooks.
In South Carolina, Attorney General Alan Wilson won the Republican gubernatorial primary runoff. Wilson, endorsed by several Republican representatives, will face state Rep. Jermaine Johnson in the general election. This rematch of the 2026 governor’s race is expected to be closely watched.
In Utah, former U.S. Rep. Ben McAdams won the Democratic primary in the 1st District. McAdams will face Naval Reserve officer Riley Owen the Republican nominee, in a district Democrats hope to flip in the midterms.
The Broader Implications
The outcomes of these primaries have far-reaching implications for the political landscape. In New York, Mamdani’s success in backing progressive candidates could shift the state’s congressional delegation to the left. Nationally, the results in Maryland, South Carolina, and Utah will influence the balance of power in Congress.
As the November general election approaches, all eyes will be on these key races. The victories of Mamdani-backed candidates in New York signal a potential sea change in the state’s political dynamics, while the outcomes in other states will shape the national political landscape.
