Arizona Gov. Katie Hobbs' reelection campaign launched its first television attack ad against Republican gubernatorial nominee Rep. Andy Biggs, R-Ariz., accusing the congressman of downplaying inflation while backing a proposal the campaign says would raise costs for Arizona families, The Hill reported on Wednesday.

The 30-second spot, titled "No Clue," began airing after Biggs secured the Republican nomination Tuesday and marks the opening salvo in what is expected to be one of the nation's most closely watched gubernatorial races.

The ad opens with audio from a television news report stating, "Inflation rose 4.2% over the past year," before cutting to Biggs saying, "No inflation, and yet the tariffs seem to be working."

"More like, no clue," the narrator says. "Biggs does have a plan to raise prices 23% more. A sales tax on everything. Gas. Groceries. Rent. A Biggs tax hit on family budgets."

The advertisement attacks Biggs on two fronts: his defense of President Donald Trump's tariff policies and his support for the FairTax Act of 2025, legislation that would replace federal income, payroll, and gift taxes with a 23% national sales tax while eliminating the Internal Revenue Service.

The Hobbs campaign argues the proposal would increase the cost of everyday purchases, calling it "100% wrong for Arizona."

"Andy Biggs says there's 'no inflation,' then turns around and champions a 23% sales tax that would make everyday essentials even more expensive for Arizona families," Hobbs campaign spokesman Michael Beyer said in a statement. "Arizona families can't afford another Washington politician making life more expensive."

Biggs, a former chairman of the House Freedom Caucus and a longtime ally of Trump, has defended the president's tariff agenda, arguing it has helped lower inflation and reduce the cost of commodities.

The ad underscores Democrats' broader strategy of making affordability and cost-of-living issues central to their midterm campaigns as they seek to capitalize on voter concerns about the economy, according to The Hill.

Biggs, who defeated Rep. David Schweikert, R-Ariz., in Tuesday's Republican primary, has attempted to present himself as a conservative willing to work across party lines.

Though Biggs supports the FairTax Act, which he co-sponsored in Congress, the legislation has not advanced in the House.

Trump endorsed Biggs during the Republican primary, as did the late conservative leader Charlie Kirk and Kirk's wife, Erika.
