Our verdict

LiberalMind endorses Kimberly Yee

Election Day is November 3. Correction, stated prominently because inventories in circulation still get this wrong: incumbent Superintendent Tom Horne is NOT on the general-election ballot. He lost the July 21 Republican primary to State Treasurer Kimberly Yee — the Associated Press called the race on the evening of July 22 — and any guide that lists Horne as the Republican nominee for superintendent is wrong. The actual race is Yee, a former Senate majority leader and Senate Education Committee chair now finishing two terms as state treasurer, against Teresa Leyba Ruiz, a 35-year educator and former community-college president, over the future of Arizona's universal Empowerment Scholarship Account program. The only public poll located has it 40–37 — the closest statewide race in that survey. This is the whole race, claim by claim. LiberalMind endorses Kimberly Yee. Read the research, and see why.

How Arizona got here

The office heads the Arizona Department of Education, distributes state and federal education funds, and sits on the State Board of Education; it is limited to two consecutive terms (Arizona Republic candidate guide, Sept. 28, 2026). The central general-election issue is the universal Empowerment Scholarship Account (ESA) program, at roughly $7,000–$10,000 per student (same).

The primaries, July 21, 2026. On the Republican side, incumbent Tom Horne — superintendent 2023 to present in this stint, previously superintendent 2003–2011 and attorney general 2011–2015, in public life since a 1979 school-board win — lost to Kimberly Yee. The primary fight was "contentious, with the pair butting heads over the state's Empowerment Scholarship Account program and diversity, equity and inclusion policies" (Arizona Republic, July 21, 2026). Pre-primary polling (NextGen): July 8–9 — Yee 44%, Horne 36%; June 16–17 — Horne 33%, Yee 24%, undecided 42% (Wikipedia, 2026 Arizona Superintendent of Public Instruction election). One partisan account claims Yee was backed "to push out incumbent Tom Horne because Tom dared to put some limits on the ballooning ESA program" — a pro-Ruiz Medium essay's framing, printed here as a partisan source's motive claim; the Republic's own primary account says the pair clashed over ESAs and DEI without adopting that motive, and we follow the Republic. On the Democratic side, Teresa Leyba Ruiz beat Brett Newby "by a wide margin" (Arizona Republic).

The confirmed general-election roster: Kimberly Yee (R) and Teresa Leyba Ruiz (D) — full ballot name per the county compilations is Teresa Leyba Ruiz; she is listed in some sources as "Teresa Ruiz" or "Dr. Terry Ruiz" — plus two write-in candidates who are not printed on the ballot: Gerard Davis (Green) and Stephen Neal Jr. (No Labels) ("Write-in candidates Gerard Davis (Green) and Stephen Neal Jr. (No Labels) are also running" — the Decent Ballot, citing Secretary of State information; FOX 10: "officials with the Arizona Secretary of State's Office say there are two other candidates in this race: Gerard Davis and Stephen Neal Jr."). The roster is corroborated by the Maricopa County ballot compilation built from official listings.

Competitiveness: Noble Predictive Insights, August 13, 2026, 923 likely voters: Yee 40, Leyba Ruiz 37 (Phoenix Courier poll table) — the closest of Arizona's statewide races in that survey. No later public poll was located in this research, and no finance totals for Yee or Leyba Ruiz were located — both gaps printed, not filled.

Kimberly Yee (Republican) — a proven officeholder moving to the office she legislated for

Background and service: State Treasurer 2019 to present (term-limited there); former state senator — Senate majority leader — and state representative; she chaired the Senate Education Committee; and she was a candidate for governor in 2022 (Wikipedia; Arizona Republic). That is a proven record across both the legislative and executive sides of Arizona government, including the chairmanship of the committee whose subject is this office.

Her positions, in the record: Support for parental involvement, school choice and the universal ESA program; the financial-literacy standards she sponsored as a legislator; on social-emotional learning (SEL), she says SEL programs raise "significant privacy concerns about the personal data of students and families" and she would "focus on core subject areas" (Arizona Republic, Sept. 2, 2026). She promised to "end the current chaos" at the Department of Education (the Decent Ballot's summary of her campaign). One biographical fact, stated as fact because it is one: Yee is not a classroom educator. Her opponent's central attack — "somebody who has never spent a day inside a classroom," per Leyba Ruiz in the same Republic piece — is campaign rhetoric built on that documented biographical fact, and we price it exactly that way: the fact is true, the conclusion drawn from it is the opponent's argument.

Pros: Proven in service at every level below this one — legislator, majority leader, education-committee chair, and two terms running a statewide executive agency. Her signature issues are this office's issues: parental involvement, school choice, the universal ESA defended as a program rather than merely audited as a problem, and a privacy-based argument on SEL that names a specific concern (student and family data) instead of a vibe. She has already beaten an incumbent of her own party to stand here.

Cons: She has never taught, and the Department of Education is the one statewide office where that absence is most legible to voters. Her "end the current chaos" promise is a campaign summary, not a costed plan, in the record located. On the only poll located, she leads by three points, inside any reasonable margin.

The flaw, plainly: No proven flaw in service was sourced against her in this file. The classroom-absence fact is biographical, priced above at its true weight: it is a résumé gap her opponent is entitled to argue from, not a demonstrated failure in office.

Teresa Leyba Ruiz (Democratic) — a proven educator, unproven in elective office

Background and service: A lifelong educator: former math teacher; president of Glendale Community College until 2023; 35 years in education (Arizona Republic; FOX 10). That is a proven record — in education administration and the classroom, the two places her opponent's record is thinnest. It is her first run for statewide office: unproven in elective office, priced as a posture, not a demerit.

Her positions, in the record: Audit and add transparency to the ESA voucher program; increase state funding for public schools; restore trust in educators and rebuild the teacher pipeline; count student growth in school letter grades; higher teacher pay (The Ballot Brief; the Decent Ballot). On SEL, she says it is "about relieving the mental health crisis students are facing," citing the bipartisan 2021 law requiring mental-health content in health education (Arizona Republic, Sept. 2, 2026). She calls herself "the only educator in the race" (the Decent Ballot) — on the sourced biographies, that self-description is accurate.

The Manchin-test fact, stated plainly: Leyba Ruiz has never held elective office, so there is no in-service record of breaks with her party to inspect; her stated program — audit the ESA program, more state funding, the educators' agenda — is her party's standard program for this office, with no break from it located in this research.

Pros: Thirty-five years in education, from a math classroom to a college presidency, is the deepest subject-matter file in the race, and her ESA position is the moderate version of her party's: audit and transparency, in her stated words, rather than abolition. Counting student growth in letter grades and rebuilding the teacher pipeline are specific, checkable proposals.

Cons: Unproven in elective office and in running a state agency of this size. Her program is her party's standard, and the audit-first posture toward the universal ESA places her, on the sourced record, against the school-choice direction Arizona's voters and Legislature have already chosen — the central question of this race, on which she and we disagree.

The flaw, plainly: No proven flaw was sourced against her in this file. The doctrinal statement is the whole of it: an unproven-in-office Democrat running her party's standard program on the race's central issue, against a proven officeholder running ours.

The write-in candidates, briefly

Gerard Davis (Green, write-in) and Stephen Neal Jr. (No Labels, write-in) — both confirmed as running by the Secretary of State's information via the Decent Ballot and FOX 10. Neither name is printed on the ballot; a vote for either must be written in. No further biographical or program material on either was located in this research, and we invent none.

OUR CALL

LiberalMind endorses Kimberly Yee.

The reasoning, stated in the piece. Strip the Horne confusion away — he is not in this race — and the choice is between two genuinely credentialed women whose credentials point in opposite directions on the central question. Leyba Ruiz's 35 years in education are real, and we steelman them above without discount; but the superintendent's job in 2026 Arizona is, first, a policy job about the universal ESA and parental authority in schools, and on that question her program is her party's standard — audit-first skepticism toward the choice program, more state funding, the SEL framework Yee challenges on privacy grounds — with no in-service break anywhere in her file to earn the Manchin exception, because she has never been in service to break from. Yee's record is proven where the test looks: majority leader, education-committee chair, two terms as a statewide executive, sponsor of the financial-literacy standards she still runs on, and a stated defense of the universal ESA and parental involvement. Her résumé gap — never a classroom teacher — is a true biographical fact, and it is outweighed, in our pricing, by proven governance in the exact policy field. Endorse the proven officeholder, flaws printed in full above.
