Redistricting

2025-2026

See also: Redistricting in Ohio ahead of the 2026 elections

Ohio was required to redraw its congressional district boundaries ahead of the 2026 elections due to a constitutional amendment that gave shorter expiration dates to maps passed without bipartisan support. On October 31, 2025, the Ohio Redistricting Commission voted unanimously to approve a new congressional map. The map will take effect for the 2026 elections.[9] The legislature had the first opportunity to pass a map with bipartisan support and did not. Had the commission not approved a map by the end of October, the legislature could have passed a map by a simple majority vote.[10]

2020-2021

See also: Redistricting in Ohio after the 2020 census

After the 2020 census, Governor Mike DeWine (R) signed a new congressional map into law on November 20, 2021.[11] The Ohio State Senate voted 24-7 to approve the map on November 16.[12] The Ohio House of Representatives voted 55-36 to approve the map on November 18.[13]

On January 14, 2022, the Ohio Supreme Court struck down the state's enacted congressional map and ordered the Ohio State Legislature to redraw it.[14] On February 9, 2022, legislative leaders said they would not draw a new map, meaning the Ohio Redistricting Commission assumed responsibility for drawing the map.[15]

On September 7, 2023, the Ohio Supreme Court dismissed a lawsuit challenging the state's congressional district boundaries after the petitioners who filed the original lawsuit requested that the court dismiss the case and leave the boundaries in place for the 2024 election.[16]The U.S. Supreme Court had vacated a 2022 state supreme court decision that had overturned the state's 2022 congressional district boundaries[17] Since the congressional district boundaries that the state's redistricting commission adopted in March 2022 and which were used in the 2022 elections did not have support from members of the minority party, they were in effect for only two U.S. House elections with the commission required to enact a new map after the 2024 elections.

On March 2, 2022, the Ohio Redistricting Commission approved a redrawn congressional map in a 5-2 vote along party lines, meaning the map lasted for four years.[18] On March 18, the Ohio Supreme Court ruled that it did not have jurisdiction to overturn the map before the state's primary elections as part of the legal challenge that overturned the initial congressional map.[19] This map took effect for Ohio's 2022 congressional elections.

How does redistricting in Ohio work? In Ohio, the state legislature or a commission may have the opportunity to draw congressional maps. A bipartisan state legislative commission draws state legislative maps. A six-member advisory commission is involved in both the congressional and state legislative redistricting processes.
