Trump and Mamdani face critical tests as primaries unfold across four states on Tuesday
Primary elections and runoffs scheduled for Tuesday across New York, Maryland, Utah, and South Carolina will serve as a crucial barometer of political influence for two leaders operating at opposite ends of the ideological spectrum. President Donald Trump and New York City Mayor Zohran Mamdani, though not appearing on any ballot, have staked considerable political capital on the outcomes. The results could either validate their ability to shape their respective parties or expose the limits of their sway over voters and party establishments.
Trump made a last-minute strategic decision in the South Carolina gubernatorial runoff, endorsing both candidates vying to replace term-limited Republican Governor Henry McMaster. The president announced support for both Lieutenant Governor Pamela Evette, whom he had previously backed alongside McMaster, and longtime state Attorney General Alan Wilson. Trump justified the dual endorsement by stating he could not hurt either candidate by supporting only one, declaring voters “can’t go wrong” with either choice.
Socialist mayor backs progressive slate in New York congressional races
Mamdani, who shocked the political establishment with his Democratic primary victory last year before winning the mayoral race in the nation’s largest city, is now attempting to leverage his popularity to reshape congressional representation. The 34-year-old socialist leader has endorsed a slate of progressive candidates challenging entrenched Democratic incumbents in multiple districts. His involvement represents a direct confrontation with party leadership and traditional power structures within the Democratic establishment.
The highest-profile challenge features political organizer Darializa Avila Chevalier, who is taking on Representative Adriano Espaillat in New York’s 13th Congressional District, which encompasses the northern third of Manhattan and a portion of the Bronx. Espaillat, 71, currently chairs the Congressional Hispanic Caucus and has served in Congress for a decade. He enjoys backing from New York Governor Kathy Hochul and other party leaders. Avila Chevalier, 32, has characterized a potential victory as a “domino” that could build “socialist power” nationwide.
Three competitive races test progressive movement strength
Mamdani has also thrown his support behind former New York City Comptroller Brad Lander, who competed against the mayor in last year’s crowded primary field before becoming one of his strongest allies. Lander is challenging incumbent Democratic Representative Dan Goldman in the 10th Congressional District, which includes Lower Manhattan and sections of Brooklyn. Goldman counts former House Speaker Nancy Pelosi among his supporters, highlighting the establishment backing he commands.
The third Mamdani-endorsed candidate, state Assembly Member Claire Valdez, is competing in New York’s 7th District against Brooklyn Borough President Antonio Reynoso. The district covers parts of Brooklyn and Queens, and Reynoso has secured the endorsement of retiring Representative Nydia Velazquez. Both Avila Chevalier and Valdez, like Mamdani, are members of the Democratic Socialists of America.

Valdez has emphasized that voters are seeking Democratic candidates with moral clarity on Israel, and the three congressional primary contests have focused significantly on anti-Israel positions. Mamdani recently referred to AIPAC, a prominent pro-Israel lobbying organization, as “monsters.” The mayor rallied with all three candidates and Senator Bernie Sanders of Vermont last week, declaring that the Democratic Party “must change.”
High stakes gamble could establish or undermine mayoral influence
The electoral bet carries substantial risk for Mamdani, who could emerge either as a kingmaker capable of reshaping Democratic representation or as a leader whose political reach has been overestimated. Six months into his tenure as mayor, he has managed to convert former critics within the Democratic establishment, including Governor Hochul, into allies. Even Trump has moderated his rhetoric, shifting from labeling Mamdani a “communist lunatic” last year to praising him as a “very rational person” who would do a “really good job” during an Oval Office meeting in November that attracted significant national attention.
Longtime Democratic strategist Joe Caiazzo, a veteran of Sanders’ 2016 and 2020 presidential campaigns, observed that Mamdani clearly understands how to leverage political power. He noted the mayor remains extremely popular and appears to recognize that such popularity may not last indefinitely, making the current moment opportune for flexing political muscle. The candidates Mamdani supports, including several running for state legislative positions, largely echo the mayor’s platform emphasizing affordability in a city with one of the nation’s highest costs of living.
Republicans see opportunity to weaponize socialist endorsements
Republican strategists view Mamdani’s high-profile involvement as ammunition they can deploy as they work to maintain their narrow House majority in the midterm elections. National Republican Congressional Committee National Press Secretary Mike Marinella characterized Mamdani’s socialist brand as toxic, arguing that at a time when Democrats lack clear leadership or messaging, he represents exactly the kind of figure Republicans can use to demonstrate who truly leads the Democratic Party and the policies they support.
Trump’s dual endorsement strategy in South Carolina mirrors previous instances where he has backed multiple candidates in the same Republican primary. The most notable example occurred in the 2022 Senate primary in Missouri, where Trump endorsed “ERIC” in a race featuring two major candidates with that first name. The South Carolina gubernatorial runoff had been viewed as another test of Trump’s grip on the Republican Party and the power of his endorsements in nominating contests. By endorsing both candidates, he effectively hedged his position while maintaining the appearance of influence regardless of the outcome.
