RENO, Nev. (News 4 & Fox 11) — We're another step closer to a rematch between President Biden and Donald Trump after the former president won Nevada's GOP caucus Thursday night.

Trump, who was the only prominent candidate participating in the Silver State's caucus, is fighting for all of Nevada's 26 delegates. Pastor and businessman Ryan Binkley was also on the ballot but needs to receive at least 4% of the vote in order to receive one delegate.

Former South Carolina governor Nikki Haley, Trump's biggest challenger on the Republican side, opted for the state's primary and lost to ballot option "none of these candidates" on Tuesday night.

On the Democratic side, President Joe Biden handily won his party's primary Tuesday which prompted author Marianne Williamson to suspend her campaign on Wednesday.

Though Trump has been the front-runner, Nevada’s caucuses were seen as especially skewed in his favor due to the intense grassroots support caucuses require candidates to harness around a state in order to win. Nevada’s state party last year barred candidates from running both in the primary and caucuses and also restricted the role of super PACs like the groups that were key to Florida Gov. Ron DeSantis’ campaign before he dropped out.

Caucuses typically require voters to show up for an in-person meeting at a certain day or time, while elections can offer more flexibility to participate, with polls open for most of the day on Election Day along with absentee or early voting. Nevada Republicans said they wanted certain rules in place like a requirement that participants show a government-issued ID.

Trump’s supporters waited in long lines Thursday. At one caucus site at a Reno-area elementary school, a line of nearly 1,000 people stretched around the corner and down the street 20 minutes after the caucuses opened.

Voters in line, some of whom were wearing Trump hats and shirts, said they came out to back the former president in a contest that would give him a third straight win in the Republican presidential race.

“I think it’s about backing Trump up and giving him the support that he needs. And to let people know that we’re supporting him,” said Heather Kirkwood, 47.

Trump has long been immensely popular among Nevada Republicans, but he had other perceived advantages among the party’s key figures. Nevada GOP Party Chair Michael McDonald and the state’s Republican National Committeeman Jim DeGraffenreid were among six Republicans in the state indicted on felony charges that they were so-called fake electors who sent certificates to Congress falsely claiming Trump won Nevada in 2020.

From Nevada, the GOP contest pivots to the South Carolina primary on Feb. 24. Trump remains popular in the deeply conservative state but Haley, who won two elections as South Carolina’s governor, is hoping to benefit from a home-state advantage. Trump is eyeing a massive delegate haul during the March 5 Super Tuesday contests, which would move him closer to becoming the GOP’s presumptive nominee.
