With 94 percent of precincts reporting, Schweikert led Quayle 53 percent to 47 percent, according to the Associated Press, which called the race for Schweikert.

Arizona gained an additional House seat following the decennial redistricting process. The new lines also prompted some reshuffling among the state’s current delegation. Quayle was faced with a choice: run in the swing 9th district or the more Republican 6th district. He chose the latter last winter, setting off a fierce competition for the seat.

As the race progressed, House Republican leadership appeared to prefer Quayle. That prompted the anti-tax Club For Growth to warn GOP leaders not to meddle in the race on behalf of Quayle. The Club said in a letter that if leadership made it clear it was behind Quayle, it would intervene on behalf of Schweikert. On Tuesday, the Club said it was pleased that House GOP leaders did not get involved.

“The House Republican leadership also deserves to be applauded for heeding our call to stay out of this race,” said Club President Chris Chocola.

Quayle is the 13th incumbent member of the House to lose in a primary so far this cycle.
