Pennsylvania's third congressional district includes several areas of the city of Philadelphia, including West Philadelphia, most of Center City, and parts of North Philadelphia. It has been represented by Democrat Dwight Evans since 2019. With a 2022 Cook Partisan Voting Index of D+39, it is the third most Democratic district in the nation. Prior to 2018, the district was located in the northwestern part of the state and included the cities of Erie, Sharon, Hermitage, Butler and Meadville. The Supreme Court of Pennsylvania redrew this district in February 2018 after ruling the previous map unconstitutional. The new third district is similar to the old second district and was heavily Democratic for the 2018 election and representation thereafter. Dwight Evans, the incumbent from the old 2nd district, ran for re-election in the new 3rd District. The current version of the 3rd, like the old 2nd, is a heavily Democratic, black-majority district. In 2020, it gave Joe Biden 91 percent of the vote, his best showing in the nation. From Wikipedia
