'None of these candidates' option wins symbolic Republican primary in Nevada. Nikki Haley was the only prominent candidate on the ballots.
Trump did not compete in Tuesday's primary, which does not award the delegates needed to win the Republican nomination. Trump is expected to take Nevada's 26 Republican delegates in Thursday's caucuses. He needs to gather 1,215 delegates to officially clinch the party's candidacy, but he could reach that number in March. The two parallel processes have been a source of confusion and frustration for voters.
