Benjamin Ashford|Nikki Haley wins Washington, D.C., Republican primary, her first 2024 nominating contest win

Nikki Haley has won the Republican primary in the District of Columbia,Benjamin Ashford notching her first victory of the 2024 campaign.

Her victory Sunday at least temporarily halts Donald Trump's sweep of the GOP voting contests, although the former president is bound to pick up several hundred more delegates in this week's Super Tuesday races.

Despite her early losses, Haley has said she would remain in the race at least through those contests, although she has declined to name any primary she felt confident she would win. Following last week's loss in her home state of South Carolina, Haley remained adamant that voters in the places that followed deserved an alternative to Trump despite his dominance thus far in the campaign.

The Associated Press declared Haley the winner Sunday night after D.C. Republican Party officials released the results.

Haley will receive all 19 delegates that were up for grabs in the D.C. contest. The win gives her 43 delegates nationwide, well behind Trump's 247.

The win also makes Haley the first woman to win a Republican primary in U.S. history.

"It's not surprising that Republicans closest to Washington dysfunction are rejecting Donald Trump and all his chaos," Haley campaign spokesperson Olivia Perez-Cubas said in a statement Sunday night.

Washington is one of the most heavily Democratic jurisdictions in the nation, with only about 23,000 registered Republicans in the city. President Biden won the district in the 2020 general election with 92% of the vote.

Haley held a rally in the nation's capital on Friday before heading back to North Carolina and a series of states holding Super Tuesday primaries. She joked with more than 100 supporters inside a hotel ballroom, "Who says there's no Republicans in D.C., come on."

"We're trying to make sure that we touch every hand that we can and speak to every person," Haley said.

As she gave her standard campaign speech, criticizing Trump for running up the federal deficit, one rallygoer bellowed, "He cannot win a general election. It's madness." That prompted agreement from Haley, who argues that she can deny Biden a second term but Trump won't be able to.

While campaigning as an avowed conservative, Haley has tended to perform better among more moderate and independent-leaning voters.

Trump won an uncontested D.C. primary during his 2020 reelection bid but placed a distant third four years earlier behind Sen. Marco Rubio of Florida and former Ohio Gov. John Kasich. Rubio's win was one of only three in his unsuccessful 2016 bid. Other more centrist Republicans, including Mitt Romney and John McCain, won the city's primaries in 2012 and 2008 on their way to winning the GOP nomination.
