The latest in Ohio

Nov. 23, 2021

Ohio adopted a brand-new redistricting process this year designed to produce fairer maps, but it doesn’t look like it made much of a difference: After blowing past two deadlines to pass a new congressional map with bipartisan support, the Republican-controlled legislature ended up passing a heavily biased congressional map all on its own. On Nov. 20, Gov. Mike DeWine signed the map into law.

While it is not as aggressive as some of Republicans’ earlier proposals, the proposed map is still highly skewed toward the GOP. The plan has an extremely high efficiency gap (a measure of which party has fewer wasted votes) of R+16 and would create 11 red seats to just two blue seats and two competitive seats.

What’s more, the two competitive seats are both just barely Republican-leaning, meaning a 13-2 Republican congressional delegation is very possible under this map. That’s even more lopsided than Ohio’s current delegation of 12 Republicans and four Democrats. The new map eliminates Democratic Rep. Tim Ryan’s swingy 13th District (from which Ryan was already retiring to run for Senate), and also converts Rep. Marcy Kaptur’s safely Democratic district into an R+8 seat. However, the map does offer Democrats a couple new pickup opportunities by making Republican Rep. Steve Chabot’s and retiring Republican Rep. Anthony Gonzalez’s districts more evenly balanced.

Because the map did not pass with any Democratic support, it will only be valid for the next two general elections. (Under the state’s new redistricting law, only a map passed with bipartisan support would be allowed to stay in place for the entire decade, but that may not matter to Republicans, since a four-year map would give them a chance to strengthen it in 2025 in response to shifting voting patterns.) The map may also have to be redrawn even sooner than that, since a group led by former Attorney General Eric Holder has filed a lawsuit in state court arguing that the map violates the partisan-fairness provisions in the state constitution.

The National Redistricting Action Fund (backed by former Attorney General Eric Holder) has challenged Ohio's congressional map in the state supreme court for violating Article XIX of the state's constitution that prohibits the state legislature from enacting a new congressional plan that "unduly favors or disfavors a political party or its incumbents."

The Ohio state House approved new congressional districts (SB 238) on a largely party-line vote. Four Republicans joined every Democrat in opposing the bill, meaning new districts will need to be approved in 2025. The new map now awaits Gov. DeWine's signature.
Who controls redistricting in Ohio in 2021?
Republicans fully control the congressional redistricting process. New maps are drawn by the Republican state legislature and enacted by three-fifths of each chamber. If the legislature fails to pass a map, redistricting falls to a bipartisan commission made up of statewide elected officials and state legislators. If the commission fails to enact a map, a new map may be passed by a simple majority of each chamber and signed into law by the Republican governor, but that map is valid for only four years.
