Chandler resident Jeff Dial and incumbent state Rep. John McComish of Ahwatukee Foothills narrowly won the Republican primary in the District 20 state House race, according to election results released Sunday by the Arizona Secretary of State's Office.
As the top two vote-getters in the four-way primary, they'll advance to the general election in November against Rae Waters, who ran unopposed in the Democratic primary. Two House members are elected from each district.
The District 20 House race was one of the closest in the state and teetered on the final tally that included provisional ballots and early ballots that voters dropped off at voting places on Tuesday.
Dial finished tops among the Republicans with 29.7 percent of the vote, while McComish drew 27.3 percent. They were followed by Tempe resident Frank Schmuck with 26.7 percent, and Andy Swann with 16.2 percent.
District 20 includes west Chandler, Ahwatukee Foothills and south Tempe.
Meanwhile, Cecil Ash and Steve Court won the four-way Republican primary in Mesa's District 18 state House race.
Ash had 38.5 percent, while Court slipped in with 25 percent. Ron Middlebrook trailed with 24.4 percent, and Kanani Henderson had 12.1 percent.
Ash and Court advance to the general election against Democrat Tammie Pursley, who ran unopposed.
In the GOP primary for the Corporation Commission, Bob Stump of Peoria had 22 percent, Barry Wong of Phoenix finished with 13.9 percent, and Marian McClure of Tucson earned 13.6 percent to advance to the general election. They finished ahead in an eight-way contest.
