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.

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.
