Pennsylvania's 8th congressional district

Pennsylvania's 8th congressional district is located in the northeastern region of the state. It encompasses all of Wayne, Pike, and Lackawanna Counties; along with portions of Luzerne and Monroe counties.

The district had been anchored in Bucks County from the 1940s until 2018, even as most other districts in Pennsylvania changed drastically during that time frame due to population shifts and Pennsylvania's loss of seats in the House.

The Supreme Court of Pennsylvania redrew the district in February 2018 after ruling the previous map unconstitutional due to gerrymandering. The 8th district was reassigned to the northeastern part of the state for the 2018 elections and representation thereafter. It is geographically the successor of the former 17th district, including the ancestrally Democratic cities of Scranton and Wilkes-Barre in the Wyoming Valley. Portions of the new 8th district also came from the old 10th district, including the more conservative counties of Pike and Wayne. Meanwhile, the Bucks County district was renumbered as the 1st district.

The district has a Cook PVI of R+4; however, the Democratic incumbent of the old 17th district, Matt Cartwright, won in 2018. It was one of five districts that would have voted for Donald Trump in the 2020 presidential election had they existed in their current configuration while being won or held by a Democrat in 2022. It is also the most Republican-leaning district held by a member of the Congressional Progressive Caucus based on the Cook Partisan Voting Index.

The district is a mix of suburban and rural communities. It is predominantly white and middle-class. The bulk of its population is located in the ancestrally Democratic cities of Scranton and Wilkes-Barre. However, the Democrats in this district are populist-leaning, different from their counterparts in Philadelphia and Pittsburgh. The old 17th swung from a 55–43 win for Barack Obama to a 54–43 win for Donald Trump, the first time much of this area had voted for a Republican since 1988.
