1950 Arizona gubernatorial election

The Democratic primary took place on September 12, 1950. Incumbent Governor Dan Edward Garvey, who ascended to the office of governor (as Secretary of State of Arizona) following the death of Governor Sidney Preston Osborn, and was subsequently elected to a full term in 1948, was defeated in the Democratic primary by State Auditor Ana Frohmiller. Frohmiller had served as state auditor since being elected in 1926, and was seen as a pioneer for women. U.S. Congressman Richard F. Harless also ran again after failing to win in 1948, as well as Jim Smith, Ralph Watkins, and perennial candidate Howard Sprouse.

U.S. Senator and Republican Presidential candidate Barry Goldwater wrote in his memoir "With No Apologies" that Frohmiller was "an attractive lady [...] who had earned quite a following as a result of her long and excellent service as State Auditor." He also observed that the voters of Arizona weren't ready for a woman Governor in 1950. Frohmiller lost the election to Pyle, who became the first Republican Governor of Arizona since John Calhoun Phillips was elected in 1928, despite the fact that at the time of her nomination she seemed to be the front-runner.
