WASHINGTON—Former South Carolina Gov. Nikki Haley secured her first GOP primary win over former President Donald Trump on March 3, winning 62.8 percent of the vote in the District of Columbia’s primary.
President Trump won 33.2 percent. Because Ms. Haley won more than 60 percent of the vote, she now gets all of the district’s 19 delegates. The district is deep blue, with 92 percent of its electorate voting for candidate Joe Biden in 2020.
