On January 22, 2018, Pennsylvania's state supreme court struck down the state's congressional district map, finding that the map constituted an illegal partisan gerrymander. On February 19, 2018, the court adopted a remedial map for use in the 2018 election cycle. Pennsylvania Republicans filed suit in federal district court to prevent implementation of the new map. The district court dismissed the suit on March 19, 2018. State Republicans also petitioned the Supreme Court of the United States to stay the state supreme court's order pending appeal. The court rejected this request on March 19, 2018.
District locations and numbers differed between the two maps (i.e., the original map, adopted by the legislature in 2011, and the remedial map enforced by the state supreme court in 2018). The map adopted by the state supreme court split 13 counties; the 2011 map split 28 counties. Had the 2018 map been in place during the 2016 presidential election, Donald Trump (R) would have won 10 districts and Hillary Clinton (D) would have won eight. In 2016, at which time the 2011 map was in place, Trump carried 12 districts to Clinton's six.
This article compares the original 2011 map and the remedial 2018 map. Map images are provided below. For more complete information on redistricting in Pennsylvania, see this article.
