Our verdict

LiberalMind endorses Mike Carey

Election Day is Tuesday, November 3, 2026, and early voting is underway in Ohio. This is the whole race — the records, the claims against each candidate, and what the sources actually show. Read the research, and decide which flaw you can live with.

The setup

Ohio's 15th District — all of Madison County and parts of Clark, Fayette, Franklin, Highland, Miami and Pickaway counties, running from Columbus's south and west suburbs (Grove City, Hilliard, Dublin) into central and southern Ohio — voted Trump 55%, Harris 45% on the new lines (Signal Ohio's new-map table; Ellis Insight describes the same seat as "a mid-50s Republican domain"). Rep. Mike Carey, who won in 2024 by 56–44, has held it since a November 2021 special election.

The expert raters and the pollsters are measuring two different races, and we print both without conflating them. Cook Political Report: Lean R. Inside Elections: Likely R. Sabato's Crystal Ball: Likely R — Cook one step closer than the other two. PollingSource's polling average, a separate instrument, reads R+2.0 and labels the race a toss-up on the polls — but every one of the three polls in that average is from Hart Research, and at least two are explicitly Democratic-sponsored (House Majority PAC); there is no independent or Republican-sponsored public poll in the record. The three: Hart for HMP, Oct 12: Leonard 48, Carey 45. Hart (D-sponsored), Aug 9, 401 likely voters: Carey 41, Leonard 37 (with Libertarian Brennan Barrington at 10%). Hart (D-sponsored), June 25, 550 likely voters: Carey 45, Leonard 40. Print the average only with that label attached, because the label is the story. The money is real on both sides: Carey has raised $4.18 million with $370,000 on hand; Leonard's current totals were not captured in our research — the Columbus Dispatch's June 30 FEC snapshot put him at roughly $600,000 raised, mostly from individual contributors, and we print it dated, as a June figure — and outside groups have spent $7.16 million, with House Majority PAC reserving $1.8 million in Columbus media against Carey.

Mike Carey (Republican)

The record: In Congress since the November 2021 special election, Carey has, in the Columbus Dispatch's summary, "rarely broken with Trump," and his campaign website prominently features the president's Truth Social endorsement of him (the Dispatch's reporting observation, printed as such). That is a followership record — stated plainly, because it is what the record shows — and in this district it is also the record the voters have twice ratified. Two documented blemishes of manner, both attributed to the district's paper of record: the Dispatch reports Carey's campaign did not respond to its multiple interview requests or its candidate questionnaire. That is the paper's account, printed as the paper states it. No scandal or verification failure for Carey was located in the sourced record.

Pros: A proven in-service incumbent whose votes are the conservative votes, in a Trump +10 seat, with a real fundraising operation and a record his district has already judged twice. Followership in a district that agrees with the leader is a lesser species of flaw than it is in a district that doesn't.

Cons: "Rarely broken" is the whole file: no documented independent stand, no signature achievement in the record we compiled, and a campaign that would not answer its hometown paper's questionnaire. A representative who cannot be distinguished from his party's whip count has outsourced the judgment the district hired him to exercise.

The flaw, plainly: Carey's flaw is followership — the right votes, cast as a matter of alignment rather than argument. It is the lightest species this publication prices, and we price it at its weight: real, named, and survivable.

Don Leonard (Democratic)

The record: Leonard, a former Ohio State University professor, has never held elected office. He beat the party's 2024 nominee, former state Rep. Adam Miller, head-to-head in the May primary, 52.9% to 47.1% — a genuine credential: party leaders viewed him as the stronger candidate (Ellis Insight's analyst judgment, printed as such), and he proved it against the man who had carried the banner before. His stated platform, from his primary-night statement: affordability across groceries, health care, child care, housing and gas. It is the standard Democratic cost-of-living program, without a documented break toward our values — none could exist, because he has never held the office in which a break is recorded.

Pros: A challenger who beat his own party's prior nominee outright rather than inheriting the slot; a focused affordability message in a district where costs are the kitchen-table issue.

Cons: He is unproven — no office, no votes, no record — carrying his party's program and its caucus. The polling that shows him competitive is entirely his own side's sponsored work.

The flaw, plainly: Leonard's flaw is emptiness, the same species as the other unproven challengers in this series: an untested candidacy asking a Trump +10 district to organize the House for his party on the strength of a primary win and a cost-of-living platform.

Brennan Barrington (Libertarian)

Barrington won his party's nomination unopposed and appears in the Dispatch's general-election guide and in the full-ballot polling (10% in the August Hart poll, 3% in June's). His ballot status rests on those compilations this pass rather than the certified Secretary of State list read directly, and no record beyond his candidacy was located. He is a ballot presence the polls have measured, not a documented campaign.

OUR CALL

LiberalMind endorses Mike Carey.

The comparison is the series standard. Carey is a proven in-service conservative whose documented flaw is followership — he votes the program his district elected him to vote, and declines to explain himself to the local paper. Leonard is an unproven challenger carrying the opposing party's program and caucus. The call is made on the records that are complete. A Trump +10 district, a proven vote for its values, and an empty opposing file — that is an endorsement, with the incumbent's followership named in the headline where it belongs.
