Rep. Andy Biggs (R-AZ) is winning the Arizona Republican gubernatorial primary by double digits, according to a poll exclusively obtained by Breitbart News.

A Pulse Decision Science survey, obtained by Breitbart News, found that Biggs leads businesswoman Karrin Taylor Robson 55 to 31 percent, with 14 percent of likely Republican primary voters remaining undecided.

Biggs and Robson aim to replace Gov. Katie Hobbs (D-AZ) as leader of the Grand Canyon State.

The survey found that if Rep. David Schweikert (R-AZ) entered the race, he would be in third place at 11 percent, with Biggs leading Schweikert by 38 percent in a head-to-head matchup.

Drew Sexton, a spokesman for Biggs, said in a statement in August:

Congressman Andy Biggs enters August as the clear favorite in the GOP Primary Election and stands well-positioned as the strongest candidate to defeat Katie Hobbs in November 2026. He's the only candidate to be endorsed by President Donald J. Trump and Charlie Kirk, the only candidate with an impeccable conservative voting record, and the only candidate with the governing experience at the state and federal level to provide strong leadership for Arizona from Day One.

Biggs also has the backing of the conservative grassroots; Turning Point USA's PAC spent roughly $500,000 on Biggs' behalf in the second quarter of 2025.

The Pulse Decision poll contrasts with a survey conducted by Noble Predictive Insights, which found that 37 percent of registered Republicans preferred Robson, while Biggs had 27 percent back from GOP voters, and 36 percent remained undecided. However, polling firms traditionally treat surveys conducted using likely voters as more reliable than simply registered voters.

Rep. Eli Crane (R-AZ) recently spoke of Biggs' ability to spread a conservative message without creating enemies.

"I don't know if you've ever spent much time with Biggs. But unlike a lot of America First fire-breathers that fire up the crowd, Biggs is kind of a happy warrior," Crane said of Biggs.

He added, "He's got friends everywhere, and it's not to say that there are some people that you know are in opposition to him, but he doesn't pick personal fights with people. He keeps everything professional."
