Former President Donald J. Trump glided to victory in Nevada’s Republican caucuses on Thursday, an outcome all but guaranteed because he was the only major candidate on the ballot.
The Associated Press declared Mr. Trump the winner shortly after caucus sites closed in Nevada, giving him his fourth straight triumph in a Republican nominating contest that awards delegates this year.
Even in a campaign in which Mr. Trump’s dominance has sapped the race of much of its drama, his win in Nevada felt particularly preordained. His last significant G.O.P. rival, Nikki Haley, opted months ago to skip the caucuses, which were run by the Nevada Republican Party, and participated instead in a primary election on Tuesday required by state law.
