Ohio Passes a New Congressional Map
While Ohio did not undertake mid-decade redistricting in response to President Trump's call to Republican controlled states to redraw maps, the state was obligated to redraw its congressional map under State law. A mid-decade redraw was required because the 2021 map lacked bipartisan support under Ohio’s 2015–18 constitutional reforms, which require any map passed without bipartisan supermajorities in the legislature or at least two Republican and two Democratic votes on the Ohio Redistricting Commission to be valid for only four years. The commission’s unanimous vote also blocks a citizen-referendum challenge that could have delayed implementation. Lawmakers had until Sept. 30, 2025, to produce a replacement map, but failed, ceding responsibility to the Ohio Redistricting Commission. The map adopted by the commission on October 31, 2025, will likely increase the number of Republican congressional districts by 2.
