States redraw both legislative and congressional districts every 10-years based on the latest U.S. Census data.
In 2015, Ohio voters approved an amendment reforming how state legislative districts are drawn. Ohio has used a winner-take-all system. The political party that controls three of five seats on the Ohio Apportionment Board has been in control of drawing legislative district maps. Since 1991, the Republicans have held control.
The General Assembly, in turn, draws the congressional district maps. The result has been lopsided, gerrymandered districts that are drawn to favor one party over another.
Ohio Gov. John Kasich and Secretary of State Jon Husted have both advocated for changes that would usher in a more fair system.
