2020 Pennsylvania House Election Interactive Map

All US House seats to be contested in 2020

Pennsylvania has 18 congressional districts, split 9-9 between the two parties. This partisan balance came about after court-ordered redistricting was put in place for the 2018 elections to reduce what was determined to be an illegal gerrymander.

2020 will be the final election with this map, as redistricting will occur in 2021 after the 2020 Census. Pennsylvania is expected to lose a congressional district. The new districts will be first contested in the 2022 election.
