Ohio's 1st Congressional District: The Toss-Up Race That Could Decide the House

Every two years, a handful of House races decide which party controls Congress. In 2026, Ohio's 1st Congressional District is one of them.

After Ohio's redistricting commission unanimously approved a new congressional map in October 2025, this Cincinnati-based district shifted from leaning Democratic to a genuine toss-up. Cook Political Report, Inside Elections, and Sabato's Crystal Ball all agree: this is one of the most competitive races in the country.

The numbers explain why. This is one of fourteen Democratic-held House seats that Trump won in 2024. The new boundaries push the district further north into conservative Warren County and Clinton County, replacing left-leaning Hamilton County suburbs with deep-red territory. Republicans originally pushed a map that would have given them thirteen to fifteen Ohio seats, but a bipartisan compromise on the redistricting commission produced a more moderate result. Still, the math got harder for Democrats.

The Democratic Primary

Incumbent Greg Landsman enters the primary as one of the strongest Democratic incumbents in a swing seat anywhere in the country. He flipped this seat in 2022 by defeating thirteen-term Republican Steve Chabot, then expanded his margin in 2024 to 55-45. His legislative record emphasizes bipartisan work: rail safety legislation after the East Palestine derailment, a $35/month insulin cap for people under 26, pharmacy benefit manager transparency, and the Veterans Suicide Prevention Act. He called on Biden to step aside in July 2024, demonstrating a willingness to break with his own party.

He has $1.83 million in receipts and $1.5 million cash on hand, dwarfing every other candidate in the race on either side.

His primary challenger, Damon Lynch, is running a grassroots progressive campaign with zero corporate PAC money, zero AIPAC money, and zero dark money. His platform covers healthcare for all, fair wages, climate justice, and opposition to unconditional military aid. The challenge is financial: Lynch has reported zero dollars to the FEC as of December 31, 2025. Whether his message-first approach can overcome the fundraising gap in a district where name recognition matters is the central question of the Democratic primary.

The Republican Primary

The Republican side features a genuine two-horse race between Eric Conroy and Steven Erbeck.

Conroy is a former CIA case officer and Air Force special operations captain endorsed by U.S. Senator Bernie Moreno. His campaign leans on biography and standard Republican positioning: border security, energy independence, fiscal responsibility, and pro-crypto policies. He has raised $600,000 with $400,000 cash on hand.

Erbeck is a Mason-area dentist and the most policy-specific Republican candidate in the field. He has detailed positions on healthcare (transparency, cross-border insurance sales, expanding HSAs, PBM accountability), housing (deregulate and increase supply), and tax policy. Despite raising less overall ($560,000), he has more cash on hand than Conroy ($460,000), suggesting more efficient spending.

Holly Adams, who worked with Turning Point USA Faith from 2022 to 2024, self-funded $400,000 but showed zero FEC dollars through December. Rosemary Oglesby-Henry, a community organizer who founded a nonprofit serving over three thousand young families, brings a unique perspective but has raised only $42,000.

The Bigger Picture

This race doesn't exist in isolation. Ohio politics in 2026 is shaped by several converging storylines.

The FirstEnergy bribery trial, possibly the biggest corruption case in state history, continues in Akron. Former CEO Chuck Jones and former senior vice president Mike Dowling face charges for funneling $4.3 million to former PUCO chairman Sam Randazzo as part of a broader $60 million scheme to pass House Bill 6, a $1.3 billion ratepayer-funded nuclear bailout. U.S. Senator Jon Husted testified as a defense witness this week, with Democrats already eyeing the footage for campaign ads in the November Senate special election against Sherrod Brown.

Meanwhile, a court blocked over $1 billion in unclaimed funds from being used for the Cleveland Browns' $2.4 billion stadium project. Governor DeWine delivered his final State of the State address focused on children's safety. And Ohio's hemp industry is fighting a ban with a signature deadline of March 19.

What Voters Should Know

The primary is May 5, 2026. Voter registration deadline is April 6. Early voting runs April 7 through May 3. Polls are open 6:30 AM to 7:30 PM EST on Election Day.

Regardless of where you fall politically, this is a race worth understanding. The candidates, the redistricting, the money, and the broader Ohio political landscape all intersect here.
