June 23 (UPI) — Mamdani-backed progressives scored big wins Tuesday night in New York state’s Democratic primary, as voters cast ballots across the Empire State, Maryland, Utah and South Carolina.

New York State

Of the four states holding primaries, New York state’s was being closely watched to gauge the influence of New York City Mayor Zohran Mamdani, who had endorsed three progressive candidates in competitive Democratic races — all of whom appeared poised late Tuesday to win their races.

Brad Lander, a former city comptroller, was running against Goldman in New York District 10 with the endorsements of other big-name progressives, including Sen. Bernie Sanders, I-Vt., and Rep. Alexandria Ocasio-Cortez, D-N.Y.

Lander said he was drawn to challenge Goldman because Goldman had called for increasing U.S. support for Israel. Their differing views on support for Israel have been a key issue in the race. Goldman and Lander are both Jewish.

Preliminary results showed Lander with an overwhelming 65.3% vote share, compared to Goldman’s 33.7%, with all 417 districts reporting.

Lander claimed victory Tuesday night.

After being introduced by Mamdani, Lander told supporters that he believes he and Goldman have more in common than they have differences. And to Goldman’s supporters, he said he knows that they want to “rescue our country back from Trumpism,” renew U.S. democracy and find a humane path for the country on the world stage.

“Solidarity is the force that we need to vanquish Trump’s fascism, to abolish ICE and to stand up to the billionaires who are rigging our economy against us,” he said.

“This campaign here was born out of solidarity.”

In New York District 7, Mamdani-endorsed Claire Valdez appeared poised to succeed outgoing Rep. Nydia Velazquez, who backed Brooklyn Borough President Antonio Reynoso.

With all 393 election districts reporting, preliminary election results showed Valdez had secured 55.5% of the vote to Reynoso’s 35.4%.

And in New York District 13, Mamdani endorsed Darializa Avila Chevalier, who late Tuesday appeared to be edging out incumbent Rep. Adriano Espaillat.

Chevalier, who was a field organizer for Mamdani, had secured 48.59% of the vote to Espaillat’s 45.2%, according to preliminary results.

Mamdani did not endorse a candidate in District 12 in a stacked field that consisted of state lawmakers Alex Bores and Micah Lasher, Lincoln Project co-founder George Conway, President John F. Kennedy’s grandson Jack Schlossberg, attorney Laura Dunn and health researcher Nina Schwalbe.

Former House Speaker Nancy Pelosi had endorsed Schlossberg and former New York City Mayor Michael Bloomberg had endorsed Lasher.

Artificial intelligence has been a central topic in the District 12 race. The Leading the Future super PAC, funded by the heads of OpenAI and venture capital firms supporting the AI industry, funneled more than $10 million to a super PAC opposing Bores’ campaign. Bores has been supportive of establishing regulations on AI.

With all 410 precincts reporting, Lasher had secured nearly 39% of the vote, followed by Bores with 34.82% and Schlossberg with 10.7%.

South Carolina

The big race in South Carolina was the GOP gubernatorial runoff between notable candidates, South Carolina Lt. Gov. Pamela Evette and state Attorney General Alan Wilson.

Preliminary results indicate Wilson stormed his way to the nomination and likely the South Carolina governor’s mansion.

With all counties reporting, Wilson netted 68.5% of the vote to Evette’s 31.44%.

Wilson has claimed victory, and Evette has conceded defeat.

The runoff followed a dramatic turnaround by President Donald Trump, who had initially endorsed Evette, before rescinding his support.

Trump gave his “Complete and Total Endorsement” to Evette ahead of the state’s primary earlier this month. But after it was determined to be a runoff between Evette and Wilson, Trump, rather than continue his support for Evette, told voters that they “can’t go wrong” with either candidate.

Evette finished less than two percentage points ahead of Wilson in the Republican primary but neither candidate cracked 30% of the vote, let alone 50%. While Trump endorsed Evette, the other candidates who ran in the primary — Reps. Ralph Norman and Nancy Mace — have endorsed Wilson. Sen. Tim Scott, R-S.C., also gave Wilson his endorsement on Friday.

“I’ve proudly stood with President Trump from the very beginning, defended him when others would not, and fought alongside him against the radical left,” Wilson said in a news release after Trump posted his support on social media. “I am deeply honored to have his support because he understands I am focused on making South Carolina more affordable for families and profitable for businesses.”

Evette’s campaign had highlighted her receiving Trump’s endorsement.

Wilson will face Democratic state Rep. Jermaine Johnson in November.

Maryland

In Maryland, Adrian Boafo was poised to succeed Rep. Steny Hoyer in the Democratic primary for District 5.

From among the two dozen candidates in the running, Boafo, Hoyer’s former field director, had nearly 32% of the vote, according to preliminary results, far exceeding healthcare CEO Quincy Bareebe, who was sitting second with 18% and former police officer Harry Dunn in third with 13.4%.

Dunn was among those defending the U.S. Capitol from attacks by pro-Trump rioters on Jan. 6, 2021. He is also a co-plaintiff in a lawsuit seeking to stop the Trump administration from establishing an “anti-weaponization fund” to pay rioters for being “targeted” by the Department of Justice.

Boafo had received Hoyer’s endorsement.

Utah

Former Rep. Ben McAdams appeared poised Tuesday night to win the Democratic nomination for Utah’s new District 1, created under Utah’s new congressional map.

Largely made up of Salt Lake City, the district went to Vice President Kamala Harris in the 2024 presidential election.

Preliminary results show McAdams with 60.2% of the vote, state Sen. Nate Blouin with 24.04% and Utah Democratic convention winner Liban Mohamed with nearly 12%.
