Pennsylvania's 6th congressional district is a district in the state ofPennsylvania. It includes almost all ofChester County and the southeastern portion ofBerks County including the city ofReading and its southeastern suburbs. The district is represented byDemocratChrissy Houlahan, who has served in Congress since 2019. As currently drawn, the district is among the wealthiest in Pennsylvania. TheSupreme Court of Pennsylvania redrew the district in February 2018 after ruling the previous map unconstitutional.^[5]

Jim Gerlach served as the district's Representative from 2003 to 2014. In 2004 and 2006, Gerlach won re-election against fellow attorney and nowMontgomery CountyCourt of Common Pleas Judge Lois Murphy. In 2008, he successfully ran for re-election against businessman and veteran Bob Roggio. In the 2010 and 2012 elections, Gerlach defeated physician andIraq War veteranManan Trivedi, the Democratic nominee.

In January 2014, Gerlach announced that he would not stand for reelection to the 114th Congress. In the race to succeed Gerlach, Chester County CommissionerRyan Costello won the Republican nomination and physician and Iraq war veteran Manan Trivedi secured the Democratic party's nomination.^[6]

In February 2018, following theSupreme Court of Pennsylvania's ordered redrawing of congressional districts, Costello announced he would not stand for reelection and retire at the end of the 115th Congress, leaving businessman Greg McCauley as the sole Republican candidate while the Democrats nominatedAir Force veteranChrissy Houlahan.^[7] Houlahan defeated McCauley in the general election.^[8]

Prior to the court-ordered redistricting, the 6th district's incarnation dated back to 2002. Its strange shape brought charges ofgerrymandering byDemocrats who argued it "looms like a dragon descending on Philadelphia from the west, splitting up towns and communities throughoutMontgomery andBerks Counties."^[10] The combination of very affluent suburban areas of Philadelphia and sparsely populated rural areas was possibly designed to captureRepublican voters, but changes in voting patterns in southeasternPennsylvania has made the district much more competitive. The district had aCook Partisan Voting Index score of R+1 after the 2012 redistricting. It was rated D+4 before then.^[11] The district included parts ofMontgomery County,Chester County,Berks County andLehigh County. The largest cities in the district wereReading andNorristown.

The redistricting of 2011/2012 changed it to include parts of Chester, Montgomery, Berks andLebanon counties. The following municipalities constituted the sixth district:^[12]

Berks County

Chester County

Lebanon County

Montgomery County
