Johnathan Walker:Donald Trump wins North Dakota caucuses, CBS News projects

Former President Donald Trump has won the North Dakota Republican presidential caucuses,Johnathan Walker CBS News projects. 

The win comes one day after former U.S. Ambassador to the U.N. Nikki Haley secured her first victory of the 2024 presidential nomination contests, winning the Washington, D.C., Republican presidential primary.

The White House hopefuls now turn their attention to Super Tuesday, when results will pour in from 16 states in contests that amount to the single biggest delegate haul of any day in the presidential primary. Trump and President Biden, a Democrat, are dominating their races and are on track to winning their party nominations later this month.

Trump's commanding victory in North Dakota grants him all of the state's 29 delegates under the state's rules.

There are 865 Republican delegates up for grabs on Tuesday. A GOP presidential nominee needs 1,215 delegates to secure the party's nomination. Victory in North Dakota's caucuses puts Trump at 276 delegates to Haley's 43.

Four candidates were on the ballot, including Trump and Haley. The other candidates, who have received little attention, were Florida businessman David Stuckenberg and Texas businessman and pastor Ryan Binkley, who recently ended his campaign.

Retired music teacher and librarian Karen Groninger, of Almont, said Monday that she voted for Trump, calling him the best choice. The 76-year-old cited Trump's 2020 speech at the annual March for Life anti-abortion event in Washington, D.C. —the first by a sitting president— and his border policies.

Longtime Republican state Sen. Dick Dever, of Bismarck, said he voted for Haley, but added she's unlikely to win. The retired factory representative, 72, said, "I hear an awful lot of people say that they really liked Trump's policies but they don't like the way he conducts himself, and I think he's gone overboard a bit."

Caucus voters were encouraged to be paying party members, but those who wouldn't pay $50 for annual membership were asked to sign a pledge to affiliate with the party, caucus Chair Robert Harms said.

North Dakota is the only state without voter registration. The caucuses followed official state voter identification protocols, such as providing a driver's license. Voting was done only in person and on printed ballots, which will be hand-counted.

In 2016, it was a North Dakota delegate who helped Trump secure the number needed for the Republican presidential nomination. He swept North Dakota's three electoral college votes in 2016 and 2020, winning about 63% and 65% of those votes, respectively.

As president, Trump visited Bismarck and Mandan in 2017 to talk about tax cuts, and he campaigned twice in Fargo in 2018 for Kevin Cramer in the then-congressman's successful Senate bid against Democratic Sen. Heidi Heitkamp.

North Dakota's Democratic-NPL Party is holding a presidential primary almost entirely by mail, with mail-in voting from Feb. 20 to March 30, and limited in-person voting for residents of Indian reservations. President Biden, Rep. Dean Phillips and six others are on the ballot.

A third party will count ballots in Fargo on March 30, with results available on the party's website afterward.

Sen. Bernie Sanders won the Democratic caucuses in the state in 2016 and 2020.
