What Redistricting Looks Like In Every State

An updating tracker of proposed congressional maps — and whether they might benefit Democrats or Republicans in the 2022 midterms and beyond. How this works »

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.

The latest in Ohio

Jan. 14, 2022

On Jan. 14, the Ohio Supreme Court invalidated the congressional map enacted by Ohio’s Republican legislature and governor in November — the first congressional map to be overturned in court so far this cycle. In a 4-3 decision, the court ruled that the map — which made 73 percent of the state’s districts Republican-leaning — violated the partisan-fairness requirement in the state constitution considering that the GOP “generally musters no more than 55% of the statewide popular vote,” in the words of Justice Michael Donnelly in the court’s opinion. “By any rational measure, that skewed result just does not add up.”

The court sent the map-drawing process back to the legislature, which now has 30 days to draw a new map. If it fails, the bipartisan Ohio Redistricting Commission would then have 30 days to take its own shot at it.

Ohio adopted a brand-new redistricting process this year designed to produce fairer maps, but it did not work out the way reformers had hoped. 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. Because the map did not pass with any Democratic support, it would only have been valid for the next two general elections.
