Mamdani flexes political muscle as progressives sweep New York primaries

TLE DESK: New York City Mayor Zohran Mamdani strengthened his standing within the Democratic Party after candidates he backed secured key victories in congressional primaries, while other contests across the United States highlighted growing battles over artificial intelligence regulation and the continuing influence of President Donald Trump.

Mamdani intervened in several Democratic House races in New York, supporting progressive challengers against establishment-backed rivals. His endorsed candidates won three major contests, including victories over two incumbent members of Congress, underlining the growing influence of the progressive wing of the party.

Among the winners was Claire Valdez, who secured the Democratic nomination for the seat being vacated by veteran congresswoman Nydia Velázquez. Another Mamdani-backed candidate, Darializa Avila Chevalier, unseated incumbent Representative Adriano Espaillat, while former city comptroller Brad Lander defeated Representative Dan Goldman after campaigning from the party’s left flank.

The victories are expected to translate into seats in Congress, given the strongly Democratic nature of the districts involved. The results also reinforce Mamdani’s influence over the party’s future direction as progressives seek a stronger voice in Washington.

Elsewhere in New York, a closely watched Democratic primary became a battleground for rival factions within the artificial intelligence industry. State Assemblyman Alex Bores, who has advocated stricter regulation of AI technologies, attracted millions of dollars in outside spending from competing technology interests.

Despite heavy financial backing, Bores was defeated by Assemblyman Micah Lasher, who was supported by Democratic leaders and pledged to remain independent of major technology companies. The race drew national attention as a test of how lawmakers may approach the regulation of rapidly developing AI systems.

In South Carolina, Trump avoided another setback in Republican gubernatorial politics by endorsing both candidates in a primary runoff. State Attorney General Alan Wilson emerged victorious over Lieutenant Governor Pamela Evette, allowing Trump to claim a successful endorsement after recent losses by his preferred candidates in governor’s races elsewhere.

Meanwhile, in Utah, former congressman Ben McAdams won the Democratic nomination in a newly drawn congressional district regarded as the party’s best opportunity in the traditionally Republican state. McAdams overcame more progressive rivals by adapting his political message to the district’s increasingly liberal electorate.

In Maryland, Democratic Governor Wes Moore secured his party’s nomination for a second term and remains widely viewed as a potential contender for the Democratic presidential nomination in 2028. Republicans selected conservative candidate Dan Cox as their nominee for governor.

The primary results highlighted shifting political dynamics within both major parties, with progressives gaining ground among Democrats while Trump continues to exert significant influence over Republican contests ahead of the 2026 midterm elections.
