With his opening campaign ad, Democrat David Garcia introduces himself to Arizona voters in two languages and tries to define his Republican rival's tenure as a "corrupt reign."

The 90-second ad begins airing Wednesday. It was shot outside Garcia's childhood home in Mesa, and aims to appeal to diverse working-class families.

Garcia has said he will be unable to rival Gov. Doug Ducey's campaign funding, and instead will have to devise and mobilize a ground game that registers and turns out thousands of new voters, particularly Spanish speakers.

The ad is running on Facebook and Twitter. His campaign spokesman declined to discuss the campaign's budget for the ad.

Garcia will face state Sen. Steve Farley, a Tucson Democrat, in the Aug. 28 primary election. The winner of the Democratic primary will face Ducey, who won the seat in 2014 and has drawn no primary challenger.

The Democratic Governors Association registered a political-action committee with the Arizona Secretary of State's Office in August, signaling that the race could draw national attention.

Garcia's ad opens with Garcia recounting his boyhood days playing outside the home where his mom still resides, as well as his military service.

"Our state is ranked No. 1 in the country in corruption and last in teacher pay," Garcia says. "Gov. Ducey's corrupt reign is wrecking our state. We're going to put an end to it, and create an economy that works for all of us.

"Our goal: great schools, good-paying jobs and honest government, for a change."

"Mejores escuelas, mejores empleos, y un gobierno honesto y justo. Join our movement, and let's write the next chapter of our story. Nuestra historia. Together."

Garcia is citing a 2014 Harvard survey that measures reporters' perceptions of government corruption. "The anecdotal reports of corruption have continued since then," said Garcia's spokesman, Bill Scheel.

Scheel also cited Ducey's ties to and friendship with a lobbyist who was named in a federal indictment and is accused of involvement in a bribery scheme. A former Arizona Corporation Commission member was also indicted in the case. The indicted lobbyist, Jim Norton, represented a client who was featured in Ducey's State of the State address earlier this year.
