James won 16 of the 17 votes cast in the Thursday evening secret ballot. Dunn, who is a precinct committee officer in the 17th, received one vote. Two officers abstained from voting.
“It’s clear that the district is ready for new leadership and I’m pleased to be their choice to work to earn their trust,” James said in a statement.
Ryan Hart, chairman of the Clark County Republican Central Committee, said he believes this is the first time 17th District Republican precinct officers have endorsed a challenger over the incumbent.
