PHOENIX (AP) — State Treasurer and former CEO Doug Ducey won the Republican primary for Arizona governor Tuesday, riding to victory with a campaign that focused on his blend of government and business experience in serving as a state official and building an ice cream company into a national brand.

Ducey started Cold Stone Creamery in Arizona and built it into a well-known chain before selling the company in 2007 and getting into politics.

He has been state treasurer for the last four years, serving as the chief steward of Arizona’s finances during a period that included the collapse of the housing market in the state.

The race to replace Republican Gov. Jan Brewer began as a fairly quiet contest focused on health care and jobs before shifting abruptly when thousands of immigrant children began pouring into the country and some settled in Arizona.

In the quest for right-leaning Republican primary voters, the six candidates quickly staked out hard-line positions on immigration and repeatedly attacked the Obama administration for failing to secure the border.
