Tuesday's primary election saw mostly known faces line up against other for seats in the U.S. House, The Arizona Republic noted.
Rep. Ben Schweikert won an "inter-family battle," defeating fellow Republican Rep. Ben Quayle.
In the battle for the Republican Senate nomination, Rep. Jeff Flake crushed Wil Cardon, a businessman who ran a self-financed campaign.
Republican U.S. Rep. Paul Gosar won the District 4, beating state Sen. Ron Gould while U.S. Rep. Matt Salmon beat former state House Speaker Kirk Adams for the District 5 position.
In District 1, Democratic former U.S. Rep. Ann Kirkpatrick will face Republican former state Sen. Jonathan Paton in November.
Quayle called Schweikert shortly before 10 p.m. to concede. The primary was one of the most closely watched in the country because it pitted two sitting congressmen against each other -- one of them the son of former Vice President Dan Quayle.
"This was an inter-family battle," Schweikert told supporters before the results were final. "I need you to reach out, whether we win or lose, to start the healing."
Redistricting after the 2010 Census gave Arizona an additional seat in Congress. The new 9th Congressional District, seen as a competitive one, includes Quayle's home in Phoenix, but he decided to run in the 6th district instead, which includes many of his former constituents.
With 85 percent of the precincts counted, Flake had 69.4 percent of the vote to 21.1 percent for Cardon. Two other candidates were in single digits.
Flake was first elected to Congress in 2000 and has been known for his fiscal conservatism. He will be running against former Surgeon General Richard Carmona, a high school dropout from New York City who went to college and medical school after Army service.
The Senate seat is open because of the retirement of Sen. Jon Kyl.
In other primary races, former state Sen. Kyrsten Sinema got the Democratic nod in District 9 and will face Paradise Vally city councilman Vernon Parker, who beat out six other Republicans.
Raul Grijalva, Trent Franks and Ed Pastor were all nominated to run for their House seats.
