Teri
Ann Hourihan

October voter guides confirmed Hourihan and running mate Angela Harrolle Mohan are on the Nov. 3 general-election ballot as the No Labels ticket. Arizona early voting commenced on October 7.

Hourihan and Republican nominee Andy Biggs faced off in Scottsdale at a Citizens Clean Elections Commission debate. Democratic Gov. Katie Hobbs and Green Party candidate Risa Lombardo did not participate. Topics included water, data centers, Medicaid, and state spending. Hourihan proposed a pause—possibly six months—on new data-center applications while the state considers impacts and needed rules, saying existing projects would continue.

At the Oct. 6 debate, Hourihan challenged Biggs over a 2013 bill concerning the Colorado City Marshal's Office that died without a Senate vote while he was Senate president, and over his initial position on releasing FBI files related to Jeffrey Epstein. Biggs disputed the Colorado City accusation, saying the bill was too broad. KTAR reported that a Snopes review found no credible evidence supporting a separate unverified allegation Hourihan raised about Biggs.

An Arizona Republic voter guide reported that Hourihan's priorities include cost of living, universal child care, school choice, accountability for education spending, and government accountability. The guide also noted her decision to run followed her behavioral-health business being removed from Medicaid after she was cleared of fraud allegations.

Hourihan selected Angela Harrolle Mohan as her running mate. Arizona's 2026 election is the first in which governor and lieutenant governor run as a joint ticket.

An ASU poll conducted in late August showed Gov. Katie Hobbs at 47%, Republican Andy Biggs at 34%, Hourihan at 2%, and Green Party candidate Risa Lombardo at 1%. A separate poll cited by Phoenix New Times showed Hobbs at 48% and Biggs at 35% but did not report Hourihan's individual figure.

Teri Ann Hourihan defeated Hugh Lytle in the No Labels gubernatorial primary. The Arizona Agenda described the result as a surprise, noting Lytle had party-leadership backing and substantial personal campaign funding. Hourihan reportedly did not have No Labels' backing after the primary, partly because she declined an interview with the party's endorsement committee.
