Election Day is November 3. Arizona has never had a lieutenant governor before. Voters approved the office in Proposition 131 in November 2022, it takes effect January 4, 2027, and there is no separate vote for it: each nominee for governor picked a running mate after the primary, and a single vote for governor is a vote for both names on the ticket. That makes this a roster note, not a separate contest — LiberalMind makes no independent endorsement in this race. The call is decided with the governor's race, and it is stated at the end. Read the four running mates' records, as far as the sources go, and see why there is nothing here to decide on its own.

How Arizona got here

Before Proposition 131, Arizona was one of five states without a lieutenant governor, and the secretary of state was first in the line of succession. Voters approved Prop 131 in November 2022 with about 55% support. Under the new system there is no separate lieutenant-governor primary and no independent candidacy: gubernatorial candidates run alone in the primary, each nominee then selects a running mate after the primary, filing a Nomination Paper with the Secretary of State no later than September 4, 2026, at 5:00 p.m. (Maricopa County officials cited August 19 as the practical ballot-preparation deadline). On the general-election ballot the lieutenant-governor nominee's name appears with and below the gubernatorial nominee's name, and a single vote for the governor counts as a vote for both (Arizona Secretary of State candidate guide, as summarized by Legal Clarity; Ballotpedia's classification of Arizona lieutenant-governor elections, 2026). Governor Katie Hobbs's General Election 2026 proclamation, issued October 2, 2026, lists among the officials to be elected November 3 "one Lieutenant Governor (elected jointly with the Governor)."

The winner succeeds the governor on death, resignation or removal and acts as governor during temporary absences — the role that previously fell to the secretary of state (Legal Clarity).

Four joint tickets are confirmed, corroborated by the Maricopa County ballot compilation built from official listings (The Decent Ballot), Ballotpedia and contemporaneous coverage: Katie Hobbs / John Giles (Democratic); Andy Biggs / Sine Kerr (Republican); Risa Lombardo / Lisa Castillo (Green); and Teri Hourihan / Angela Harrolle Mohan (No Labels Party).

The lieutenant-governor contest has no separate competitiveness evidence and no money of its own — it rises and falls with the gubernatorial tickets, which are covered in our Arizona governor coverage. The one lieutenant-governor-specific event in the record is an October televised debate for an office that has never existed — a first — at which the Democratic and Green nominees did not appear (Arizona Republic: "Two other candidates — Hobbs' pick for No. 2 and a Green Party candidate — did not attend").

John Giles (Democratic ticket) — a Republican mayor, on a Democratic ticket

Background and service: Mayor of Mesa from 2014 to 2025; he left office in January 2025. Party history, printed accurately: Giles was long a registered Republican; one 2026 account reports he later changed to no party preference (Republican Journal). He is running on the Democratic ticket. His current registration was not verified against the voter file in this research. Hobbs, announcing the pick: "I asked John Giles to join this ticket because he shares my commitment to putting Arizona first… We come from different political parties" (FOX 10 Phoenix). The Biggs campaign attacked the pick, calling Giles "an aspiring Democrat since he first voted for Joe Biden in 2020" (same FOX 10 report — campaign rhetoric, attributed as such, and priced as rhetoric, no more).

Pros: Eleven years running Arizona's third-largest city is a proven executive record, and a cross-party pick is, on its face, the kind of moderate signal our mission exists to notice.

Cons: There is no separate vote and no separate record to weigh for this office; whatever Giles would do as lieutenant governor is inseparable from the Hobbs ticket he chose to join.

The flaw, plainly: None is stated for Giles individually in the sourced record — and none is needed. This is not his race to win or lose on its own.

Sine Kerr (Republican ticket) — a senator and a farmer, picked by Biggs

Background and service: A former Republican state senator from Buckeye and a dairy farmer; most recently the Trump administration's Arizona state executive director of the USDA Farm Service Agency (Arizona Republic debate coverage; FOX 10 Phoenix). In the October lieutenant-governor debate she attacked the Hobbs administration's record (Arizona Republic).

Pros: Legislative service plus agricultural administration is a real, relevant file for a succession office in a state where water and land are governing questions.

Cons: As with Giles, there is no separate contest to judge; her candidacy stands or falls entirely with the Biggs ticket.

The flaw, plainly: None is stated for Kerr individually in the sourced record.

The minor-ticket running mates, briefly

Angela Harrolle Mohan (No Labels ticket) — a real-estate broker and former chief executive officer of The 100 Club, a nonprofit supporting families of first responders killed or seriously injured (Arizona Republic). She is running with the party's gubernatorial nominee, Teri Hourihan. Lisa Castillo (Green ticket) — running with gubernatorial nominee Risa Lombardo (Daily Letter 2026 midterm guide, built from the Arizona Secretary of State candidate listing; the Decent Ballot lists the same pairing). No biographical material on Castillo was located in this research — we print that gap rather than fill it. Neither minor ticket's lieutenant-governor nominee changes the analysis: there is no independent vote to cast for either of them.

OUR CALL

No endorsement in the lieutenant-governor race — this call is decided with the governor's race.

There is no other honest call available, because there is no other vote available. Arizona voters cannot choose John Giles without choosing Katie Hobbs, cannot choose Sine Kerr without choosing Andy Biggs, and cannot choose Mohan or Castillo without choosing their tickets. An "endorsement" of a running mate would be a fiction printed over a ballot that does not offer the choice. In our Arizona governor coverage, LiberalMind endorses neither candidate for governor and leans — narrowly, and on stated terms — to the challenger's ticket. That verdict, and only that verdict, governs this office: whoever wins the governor's race brings their lieutenant governor with them, and the succession that used to run through the secretary of state will run through a person Arizona voters never got to judge separately. That is the system Proposition 131 built. We report it as it is.
