Former Congressman Matt Salmon has beaten former Arizona House Speaker Kirk Adams to win the Republican nomination for Arizona's 5th Congressional District in southeastern Maricopa County.
Salmon was leading Adams by 54 percent to 46 percent Tuesday evening.
Democrat Spencer Morgan was unopposed in the GOP-dominated district and will face Salmon in November's general election.
The 54-year-old Salmon represented an earlier version of the district for three terms in the 1990s. He ended his tenure in Congress to follow a pledge that he would serve only three terms and went on to an unsuccessful run for governor in 2002. Salmon has worked as a lobbyist in recent years.
The 39-year-old Adams was appointed to the state House in 2006 and served as House speaker for more than two years.
