Rep. John Boozman (R-Ark.) won the Arkansas GOP Senate nomination Tuesday, beating out a field of eight candidates.

Boozman had 53 percent of the vote with 2,079 of 2,516 precincts reporting, according to unofficial results. The Associated Press declared him the winner.

National Republican Senatorial Committee Chairman John Cornyn (Texas) congratulated him on the win.

"John Boozman earned the trust and respect of Arkansans through his consistent and effective representation in Congress, where he has fought hard for policies that lower taxes, control spending, create good-paying jobs, and keep America safe," Cornyn said in a statement. "As a local business owner and community optometrist, John Boozman understands the destructive impact of the Democrats’ economic and healthcare policies for the families, seniors, farmers, and job creators in his state who are struggling to make ends meet."
