Ohio’s seven-member Redistricting Commission voted unanimously today to approve a new congressional map that will govern the state’s 15 U.S. House districts starting with the 2026 election cycle. The bipartisan deal preserves a GOP advantage and could shift the balance from the current 10-5 split to something closer to 12-3. Commissioners from both parties backed the plan to meet the Oct. 31 constitutional deadline and avoid sending map-drawing back to the legislature.
Why a new map was required: under Ohio’s 2018 reform (Article XIX), the 2021 congressional map was adopted without the required bipartisan supermajority, authorizing it to govern only up to the 2024 election, after which, a mandatory redraw in 2025 is required. Under these rules, the General Assembly must adopt a bipartisan map by Sept. 30 or cede map-drawing responsibility to the Commission. The legislature missed its Sept. 30 deadline, and the Commission took control as of Oct 1st.
Today’s approval also fits into the broader mid-decade redistricting wave. While Ohio did not undertake mid-decade redistricting in response to President Trump’s call to Republican controlled states to redraw maps, the passage of this map will likely net two additional Republican seats in the U.S. House of Representatives. This makes its enactment a key event in this unprecedented mid-decade redistricting push. Read more in the Ohio Capital Journal, Politico, Washington Post, New York Times, and wosu.org.
