Arizona primary results
Senate race
Rep. Martha McSally, the preference of the national Republican establishment, easily won the Republican primary with 52 percent of the vote. Former state Sen. Kelli Ward and former Maricopa County Sheriff Joe Arpaio trailed behind McSally.
Rep. Kyrsten Sinema cruised to victory against her Democratic primary opponent, Deedra Abboud. National Democrats were hoping that Sinema would face Ward or Arpaio in the general election, as both of them are controversial right-wing figures considered to be more beatable. Sinema will have an uphill battle with McSally as an opponent.
Regardless of who wins in November, Arizona will be sending a woman to the Senate for the first time in state history.
Gubernatorial race
Incumbent Republican Gov. Doug Ducey easily dispatched his primary opponent, Ken Bennett, with 70 percent of the vote.
Democrat Doug Garcia, an educator and military veteran, won his primary against two opponents.
CBS News rates AZ-1 and AZ-2 as competitive congressional districts as Democrats seek to flip 23 Republican seats in the House this November. The 2nd Congressional District is the seat currently held by McSally, and is considered by Democrats to be a potential pickup in November.
