Richard Carmona says he won't be running for Arizona governor in 2014.

Fred DuVal’s gubernatorial campaign is semi-official after filing an exploratory committee today, making him the first Democrat to test the waters for the state’s top office in 2014.

Fred DuVal said there is a “high probability” that he will officially begin his campaign for governor later this month.

DuVal, a former regent, former Clinton White House aide and longtime Democratic operative, said he expects to file his campaign committee with the Secretary of State’s Office by the end of February.

Former Tempe Mayor Hugh Hallman made his official entry into the 2014 governor’s race.

Hallman, a Republican, has long been an oft-rumored candidate for numerous offices. On Tuesday he filed a campaign committee with the Arizona Secretary of State’s Office for a gubernatorial run.

“We’re off and running,” Hallman said.

After 18 years at the Maricopa County Board of Supervisors, Don Stapley is setting his sights on Congress. Stapley said he filed paperwork Tuesday with the Federal Election Commission to run in the 9th Congressional District, which covers parts of Chandler, Mesa, Phoenix and Tempe.

The mayor of the third-largest city in Arizona has thrown his support behind congressional candidate Matt Salmon, a potential game-changing blow in the district’s race.

Tempe Mayor Hugh Hallman is chairing Paradise Valley Mayor Vernon Parker’s gubernatorial exploratory committee, putting an end to speculation that he might seek the job himself.
