Voters in New York, Maryland, Utah and South Carolina head to the polls Tuesday for primaries that will test the strength of outside money, the party establishment and political figures trying to sway both to their side.
The race is in New York’s 12th District, where Democrats are choosing a candidate to replace retiring Rep. Jerry Nadler in one of the safest blue seats in the country. The crowded Manhattan primary includes Assembly members Alex Bores and Micah Lasher, as well as Jack Schlossberg, the grandson of President John F. Kennedy.
Bores’ record on AI regulation and the foreign money around it has turned the race into a national proxy fight over how aggressively Democrats should regulate one of the fastest-growing sectors of the economy.
Elsewhere in New York City, Mayor Zohran Mamdani is trying to prove that his democratic socialist political movement can outlast his own campaign and reshape Congress. Upstate, the Republican primary to replace Rep. Elise Stefanik will test whether President Donald Trump’s support can overwhelm the local Republican Party.
In Maryland, Democrats are choosing a successor to former House Majority Leader Steny Hoyer, while Rep. April McClain Delaney faces a self-funded challenge from former Rep. David Trone. And in Utah, new House maps have shuffled primaries in both parties.
Here are five things to watch on Tuesday:

Is Mamdani a kingmaker?
She supported Darializa Avila Chevalier against Rep. Adriano Espaillat in NY-13, former New York City Comptroller Brad Lander against Rep. Dan Goldman in NY-10, and Assemblywoman Claire Valdez in the race to replace retiring Rep. Nydia Velázquez in NY-7.
These approvals angered parts of the Mamdani coalition.
Espaillat is the chairman of the Congressional Hispanic Caucus and a close ally of House Democratic Leader Hakeem Jeffries, also of New York. Velázquez, one of Mamdani’s early supporters, broke up with him because of Valdez. Labor unions, Latino leaders and some progressives were also outraged by his decision to challenge incumbents and their longtime allies.
But Mamdani argues that Democratic voters are more susceptible to disruption than party leaders realize.
A Honan Strategy Group questionnaire It found that only 63% of New York City Democratic voters viewed the party favorably, while 35% viewed it unfavorably. Half said electing a younger, more progressive generation willing to challenge the establishment is a top priority in this year’s primaries.
The poll also found that 43% of Democratic voters in the Big Apple say primary challenges to incumbents like Espaillat are healthy for the party, while 13% call them divisive distractions.
A win for candidates backed by Mamdani would demonstrate that the mayor, who will be term-limited at the end of 2033, is a progressive power broker beyond City Hall. Losses show that the appeal is personal, inalienable.

The money out there is testing the left
In New York, too, wars are fought over money.
In NY-13, Espaillat is trying to keep out Avila Chevalier, who has made his fight against corporate money and the corporate money of the United States the centerpiece of his campaign. Israel.
The influential pro-Israel lobby group AIPAC has become a major player through its super PAC. United Democracy Project. UDP gave $650,000 at least to BOLD America that spends $2.8 million He supports Espaillat and opposes Avila Chevalier. Other pro-Espaillat groups such as the Latin Victory Fund, Project 218, and the Progressive Unity Fund have also joined the effort.
Avila Chevalier is getting outside help from Justice Democrats and American Priorities, a pro-Palestinian super PAC created as a counterweight to AIPAC. But for the left, they say the pro-incumbency spending is also evidence that national groups are trying to separate safe Democratic seats from progressive rivals who are more critical of Israel.
The same dynamic is playing out elsewhere. A pro-Goldman super PAC, $300,000 In NY-10. In NY-12, pro-technology groups support Bores, while former New York Mayor Michael Bloomberg also supports Bores. $10 million He’s behind Lasher, his former deputy and Nadler’s approved successor.

Maryland tests establishment strength
Maryland Democrats face two very different tests of strength.
In the 5th District, Hoyer’s retirement triggered a 24-candidate primary for the seat he has held for 23 terms.

In the neighboring 6th District, McClain Delaney is trying to stop Total Wine co-founder Trone, who is leaving the seat due to his unsuccessful 2024 Senate bid. Trone loaned his campaign $25 million, two years after spending $63 million of his own money in his Senate race.

Redistricting stirs both parties in Utah
Outside of the West, Utah’s races on Tuesday are the clearest examples of how this happens. Redistricting is reshaping the fight for the House majority.
A court-ordered map created a Democratic-leaning Salt Lake City-centered 1st District, giving the party a rare chance at breaking into Utah’s all-Republican House delegation.
Former Rep. Ben McAdams, the last Democrat to represent Utah in Congress, is running against state Sen. Nate Blouin, tax attorney Michael Farrell and political newcomer Liban Mohamed.
The new lines also made it harder for Republicans to place candidates in less familiar territory and make the redistricting fight itself a primary issue. Rep. Blake Moore is facing Karianne Lisonbee in the 2nd District, while Rep. Celeste Maloy is trying to stop Phil Lyman in the 3rd District.
Beyond Utah, redistricting fights across the country are already helping determine the 2026 House battleground.

Trump faces local test in Stefanik’s old district
So far in this first season, Trump’s support carries great weight. But in upstate New York, the state is falling into the GOP machine.
In the 21st District, the race to replace Rep. Elise Stefanik has turned into a fight between first-time candidate State Assemblyman Anthony Constantino and Stick Mule CEO. supported by Trumpand state Assemblyman Robert Smullen, a retired Marine colonel who is backed by the state’s Republican establishment.
The region should be friendly ground for Trump’s election. Trump won nearly 60% of the vote in 2024, and Stefanik became one of his staunchest allies in the House.
Constantino turned to the MAGA stunt and self-funded his campaign with millions. Smullen has spent much less but has support from 12 of the district’s 15 Republican county committees and the Conservative Party line, which could keep him on the November ballot even if he loses the GOP primary.
Smullen’s win would mark a rare limit to Trump’s influence. A prolonged Republican split could leave Democrats with a narrow gap in a seat where they would otherwise have little chance.
