Ohio's 1st congressional district is represented by Republican Steve Chabot. This district includes the western four-fifths of Cincinnati, and borders both Kentucky and Indiana. This district was once represented by President William Henry Harrison. Since redistricting in 2010, the district was widely seen as heavily gerrymandered by state Republicans to protect the incumbent, Steve Chabot. However, Chabot lost the seat in 2022 to Democrat Greg Landsman.
