Warren Petersen
Poll: Arizona Senate President Warren Petersen Leads GOP Attorney General Primary

April 11, 2026

By Staff Reporter |

The leader of the Arizona Senate is one of the top contenders to unseat Attorney General Kris Mayes this November, according to a recent poll.

Arizona Senate President Warren Petersen (R-LD14) led among prospective voters polled about the upcoming primary election in the attorney general’s race. 

The poll from Gray House surveyed 400 likely Republican voters and 450 likely general election voters across the state. 

Petersen leads fellow Republican candidate Rodney Glassman, both before voters were advised of the candidates’ backgrounds and after. (The polling did include a third Republican candidate, Greg Roeberg; however, Roeberg withdrew from the race in February).

A majority of voters — 75 percent — said they were undecided prior to being informed about the candidates’ backgrounds.

After, 42 percent of the 75 percent of undecided voters put their support behind Petersen. 

65 percent of likely voters polled said they were more likely to support Petersen after hearing his biography. 

Petersen’s platform proposes a more conservative federalist approach to the attorney general’s office: defending the rule of law as opposed to acting on personal political preferences, curbing federal overreach, increasing criminal prosecutions, defending women’s sports, and protecting constitutional rights.

Petersen has served in the Arizona legislature since 2012—first in the state house, then the state senate. He also assumed a leadership role in the house; he served as the majority leader prior to his election to the state senate. 

Glassman, by contrast, lost the support of 74 percent of the voters polled after hearing his biography. 

Glassman’s platform focused on certain specific areas of interest, a continuance of the major flip he made from his years as a Democrat: prosecuting border crime and election fraud, advocating for law enforcement, defending the Second Amendment, and scrutinizing government expenditures. 

Prior to this race, Glassman ran for attorney general in 2022 as a Republican (lost in the primary), Maricopa County assessor in 2020 as a Republican (lost in the primary), Arizona Corporation Commission in 2018 as a Republican (lost in the general election), and U.S. Senate in 2010 as a Democrat (lost in the general election). 

Voters expressed indifference to Roeberg after hearing his biography, only inspiring an additional 17 percent more likely voters.

Among prospective general election voters, Petersen trailed behind Attorney General Mayes by two points, around 42 to 44 percent. 

Glassman trailed Mayes by 7 points and Roeberg trailed Mayes by 9 points. 

As state senate president, Petersen has been uniquely positioned among the candidates to challenge Mayes on her execution of the office directly. A significant portion of Mayes’ focus in office since last January has concerned fighting policies and executive orders put forth by the Trump administration.

Earlier this week Petersen referred Mayes and Secretary of State Adrian Fontes to the Department of Justice for an investigation, alleging the pair were guilty of obstruction of justice and witness tampering for meddling with a federal probe into Arizona election records. 

“The threats of the Attorney General and Secretary of State are incompatible with United States Constitution, which enshrines the grand jury in our constitutional order, and only serve to hinder voters’ confidence in our elections,” stated Petersen.

Mayes and Fontes advised the county recorders against complying with the federal subpoena.
