Ohio is divided into 15 congressional districts, each represented by a member of the United States House of Representatives. After the 2010 Census, Ohio lost two House seats due to slow population growth compared to the national average, and a new map was signed into law on September 26, 2011. This map was ruled unconstitutional as partisan gerrymandering, and state Republicans were told to redraw the map before June 14, 2019. However, on October 7, 2019, the U.S. Supreme Court dismissed the challenge to the map, allowing it to stay in effect for the 2020 election.
Current districts and representatives
On May 3, 2019, a three-judge panel from the United States District Court for the Southern District of Ohio declared the Ohio's 2012 district map contrary to Article One of the United States Constitution, as "an unconstitutional partisan gerrymander" and ordered "the enactment of a constitutionally viable replacement" prior to the 2020 presidential election. An appeal made to the Supreme Court resulted in the order to redraw the map being nullified.
