PHOENIX (AP) — State Treasurer Doug Ducey has won the Republican primary for Arizona governor, topping five other candidates with a campaign focused on his business experience in leading a chain of ice cream parlors.

Ducey started Cold Stone Creamery in Arizona and built it into a major company before selling it and getting into politics. He has served as state treasurer for the last four years.

Ducey prevailed despite his opponents questioning his record as CEO and whether he was really an effective leader of the company.

Ducey will face Democrat Fred DuVal in the November election.
