Ohio’s post-2020 congressional redistricting quickly spiraled into a back-and-forth between map-drawers and the courts. After the Ohio Redistricting Commission missed its statutory deadline, the General Assembly rushed through Senate Bill 258, and Gov. Mike DeWine signed it on Nov. 20 2021. Three lawsuits, including League of Women Voters of Ohio v. DeWine, were filed within days. On Jan. 14, 2022, the Ohio Supreme Court struck down the map as an extreme partisan gerrymander. Control shifted to the seven-member Ohio Redistricting Commission, which adopted a second plan on Mar. 2, 2022, again along party lines. The state supreme court again invalidated that plan on Jul. 19, 2022, but allowed it to stand for the midterms due to time constraints for the upcoming election. Republican leaders then appealed, and on Jun. 30, 2023, the U.S. Supreme Court granted certiorari, vacated the lower court's decision, and remanded the case in light of Moore v. Harper. Two months later, the state court dismissed the remaining claims, allowing the March 2022 map to govern until after the 2024 election. The map automatically expires after that by virtue of it not having passed with bipartisan support as required under state law. Lawmakers had until Sept. 30, 2025, to produce a replacement or cede control to the commission, but failed to adopt a map. On October 31, 2025, the Commission unanimously adopted a new map for the remainder of the decade.
Ohio's state legislative redistricting proved even more turbulent. The Redistricting Commission’s first map was adopted by a 5-2 vote on Sept. 15 2021, but was invalidated by the state supreme court on Jan. 12, 2022, for flouting proportionality rules. A second version adopted on Jan. 22 was invalidated on Feb. 7, 2022. A third map approved Feb. 24 was also struck down on Mar. 17. A fourth map, passed on Mar. 28, met the same fate on Apr. 14. When the Commission simply resubmitted an earlier plan on May 5, the Court rejected it for a fifth time. Meanwhile, facing a blown primary calendar, a federal three-judge panel ordered the use of the February map for the 2022 election only.
After a year-long stalemate, the Commission unanimously adopted a bipartisan “Map 6” on Sept. 26, 2023. The state supreme court dismissed the last challenges to the maps on Nov. 27, 2023, stressing that the cross-party vote entitled Map 6 to a full ten-year run through 2032.
