District map
Redistricting
2020 redistricting cycle
On February 4, 2022, the Pennsylvania Legislative Reapportionment Commission voted 4-1 to approve new state House and Senate maps.[6] House Majority Leader Kerry Benninghoff (R) voted no, while Senate Majority Leader Kim Ward (R), state Rep. Joanna McClinton (D), state Sen. Jay Costa (D), and chairman Mark Nordenberg voted yes.[6] These maps took effect for Pennsylvania's 2022 legislative elections.
How does redistricting in Pennsylvania work? In Pennsylvania, the statutory authority to draw congressional district boundaries is vested with the Pennsylvania General Assembly. These lines are subject to gubernatorial veto.[7]
State legislative district lines are drawn by a politician commission. Established in 1968, the commission comprises five members:[7]
- The majority leader of the Pennsylvania State Senate appoints one member.
- The minority leader of the Pennsylvania State Senate appoints one member.
- The majority leader of the Pennsylvania House of Representatives appoints one member.
- The minority leader of the Pennsylvania House of Representatives appoints one member.
- The first four commissioners appoint a fifth member to serve as the commission's chair. If the commission is unable to reach an agreement, the Pennsylvania Supreme Court must appoint a commission chair.[7]
The Pennsylvania Constitution requires that state legislative districts be contiguous and compact. Further, state legislative districts should "respect county, city, incorporated town, borough, township and ward boundaries." There are no such requirements in place for congressional districts.[7]
