Sam Brown Wins Nevada G.O.P. Senate Primary and Will Face Jacky Rosen in November

Sam Brown, an Army veteran who was the heavy favorite in the Nevada Republican primary race for Senate even before former President Donald J. Trump’s last-minute endorsement, won the nomination on Tuesday, according to The Associated Press.

He will face Senator Jacky Rosen, the state’s Democratic incumbent, in one of the most closely watched Senate contests of the year.

With 57 percent of the vote counted, Mr. Brown had 57 percent, lapping the crowded primary field. His closest rival, Jeff Gunter, a former U.S. ambassador to Iceland, had about 17 percent. Jim Marchant, a former state assemblyman, was at roughly 7 percent, and Tony Grady, an Air Force veteran, had 5 percent.

The victory was redemption of sorts for Mr. Brown, who ran for Senate in 2022 after moving to Reno, Nev., from Dallas in 2018, but lost in the Republican primary to Adam Laxalt, the state’s former attorney general. This time, he was the pick of the Republican establishment from the start, and the National Republican Senatorial Committee, which works to elect Republicans to the Senate, backed him early and worked to clear the field of competitors.

They did not quite manage that. Roughly a dozen Republican challengers vied for the right to face Ms. Rosen, a low-profile Democrat running for re-election in a battleground state where recent elections have been decided by narrow margins.

But most gained little traction, and as Mr. Brown crisscrossed the country raising money and rallying support from prominent Republicans, the other candidates failed to come close to his fund-raising totals. He also earned the endorsement of the state’s Republican governor, Joe Lombardo.
