McCain took 56 percent of the statewide vote, and nearly the same in Pima County. Hayworth received 32 percent of the vote, Jim Deakin 11 percent.
McCain now faces off in November against former Tucson City Councilman Rodney Glassman. Glassman won with support from nearly 47 percent of Democratic voters.
In the contested primary for the Republican nomination in U.S. Congressional District 8, Jesse Kelly won with nearly 48 percent of the vote. His nearest competitor, veteran state legislator Jonathan Paton, received 42 percent of the vote.
