Ohio's 4th congressional district spans sections of the northeast, central, and southwest areas of the state. Its nickname, "the duck district," refers to its gerrymandered geographical shape being similar to a duck. The district zig-zags west and south from Cleveland's suburbs to Mercer County on the Indiana border. The largest city in the district is Elyria. It also includes Oberlin, home of Oberlin College. It is currently represented by Republican Jim Jordan, who has represented the district since 2007.
