Our verdict

LiberalMind endorses John Leiber

Election Day is November 3. State Treasurer John Leiber is the only Republican holding a statewide elected office in Wisconsin, and he is running on keeping that office exactly as small as it now is — unclaimed property and a seat on the Board of Commissioners of Public Lands. His Democratic challenger, Marathon County Supervisor Yee Leng Xiong, wants to rebuild it into an auditing and transparency office, and has outraised the incumbent roughly two and a half to one. One forecast model leans Democratic; no rating-house rating was located. LiberalMind endorses John Leiber. Read the research, and see why.

How Wisconsin got here

Leiber, first elected 2022, was unopposed in the Republican primary (99.8% including write-ins in the compiled results). Xiong won the Democratic primary over Dylan Helmenstine, 57.1% (381,375) to 42.7% (284,960) (2026 Wisconsin State Treasurer election compilation). The roster — Leiber (R) vs. Xiong (D) — is the complete ballot in the sources consulted; a pre-print check against the Wisconsin Elections Commission's official list remains the standing step for any late minor-party filing.

The money (Transparency USA compilation, cumulative as displayed Oct. 2026 — the compilation's figures): Xiong contributions $94,461.50, expenditures $47,644.33; Leiber contributions $38,840.00, expenditures $5,522.46. The challenger has outraised the incumbent roughly 2.4-to-1 in this compilation — and Helmenstine, the losing primary candidate, raised $141,156.62, more than either general-election candidate. Competitiveness: the WisPredict model (accessed Oct. 25, 2026) gives Xiong a 71.7% win probability, a projected 53.2–46.8, "Lean D" — a single forecast model; no rating-house rating for this race was located. Ballotpedia News flagged the race among its "noteworthy" 2026 financial-office contests. We print the model labeled as a model and make our call on the records.

John Leiber (Republican) — the incumbent

Background and service: Treasurer since 2023 (first elected 2022), in his first term — proven as officeholder. The office's duties "have been whittled down to overseeing the state's unclaimed property program and sitting on the Board of Commissioners of Public Lands" (WORT). Leiber's position: the office does not need further responsibilities; he cites supporting the BCPL municipal loan program and a $1.6 billion common school fund during his tenure (Ballotpedia News, Oct. 21). Ballotpedia identifies this as "the only statewide elected office in Wisconsin held by a Republican" (same). The Secretary of State, Treasurer, and Attorney General all sit on the BCPL, which distributes fund money to schools, libraries, and local governments (Focal News).

Pros: A proven first-term incumbent in the exact office, defending a constitutionally modest conception of it — the treasurer as custodian, not as a second auditor.

Cons: Outraised 2.4-to-1 by his challenger in the compilation, with the single located model leaning against him. No flaw is alleged; the risk is arithmetic, and arithmetic is not a flaw.

The flaw, plainly: No flaw proven in service was located.

Yee Leng Xiong (Democratic) — the challenger

Background and service: Marathon County supervisor (also described as a county commissioner and school board member in Dane County coverage — the descriptions are printed as located; Focal News); the 2024 Democratic nominee for the 85th Assembly district (2026 Wisconsin State Treasurer election compilation). His position: expand the office — have the treasurer conduct state audits, create transparency portals on government spending, and run financial-literacy and retirement-savings education (Ballotpedia News, Oct. 21). Endorsed by U.S. Sen. Tammy Baldwin (same compilation). First-time statewide candidate — unproven at statewide level.

The Manchin test: No break with his party toward our values in service was located in this research. His program — a larger treasurer's office with audit ambitions — runs with, not against, his party's direction.

Pros: A specific, honestly stated institutional program; the money lead; a senator's endorsement; county-level service.

Cons: His program's premise is that a deliberately narrowed office should grow new powers — audits that duplicate the state's existing audit machinery — and no Manchin-test break accompanies it.

The flaw, plainly: Not a conduct flaw — a program flaw under our values: government expansion as the candidacy itself, from an unproven statewide candidate.

OUR CALL

LiberalMind endorses John Leiber.

The substantive dispute is stated plainly by both men: keep the treasurer's narrow custodial role (Leiber), or rebuild it into an auditing and transparency office (Xiong). Leiber is proven in the office, holds the one statewide seat his party holds in Wisconsin, and has no flaw proven in service located. Xiong is unproven statewide, brings no Manchin-test break, and asks voters to enlarge the office as his central promise. Under our doctrine — small, accountable offices, and endorsements earned — the incumbent's restraint is the qualification. Endorse Leiber. The model's Lean D and the challenger's money lead are printed above as the facts they are; neither changes the records.
