2018 Pennsylvania House Election Interactive Map

All US House seats to be contested in 2018
Pennsylvania has 18 congressional districts. Republicans hold 10 of them, Democrats 6. There are two vacancies; both those seats will be filled by special election (based on pre-redistricting boundaries) on November 6th.

As a result of a Court ruling, Pennsylvania's congressional district boundaries are changing for the 2018 midterm elections. Read how we're handling the 2018 Pennsylvania Redistricting. The changes make it highly probable Democrats will pick up one or more seats in November.
