2018 United States House of Representatives elections in Pennsylvania


The 2018 United States House of Representatives elections in Pennsylvania were held on November 6, 2018, to elect the 18 U.S. Representatives from the Commonwealth of Pennsylvania, one from each of the state's 18 congressional districts.
The elections coincided with the 2018 gubernatorial election, as well as other elections to the House of Representatives, elections to the United States Senate and various state and local elections.
In January 2018, the Pennsylvania Supreme Court struck down the state's congressional map, ruling it had been unfairly gerrymandered to favor Republicans. New maps were subsequently adopted in February 2018.
The 2018 general election saw the Democrats gain four seats and the Republicans gain one seat, for a Democratic net gain of three seats, changing the state's representation from 12–6 Republican to a 9–9 tie. In addition, Pennsylvanians in several districts elected female candidates to the U.S. House, thus ending four years of all-male Congressional representation in the state.

Redistricting

In January 2018, the Pennsylvania Supreme Court struck down the state's congressional map, ruling it had been unfairly gerrymandered to favor Republicans. New maps were subsequently adopted in February 2018, for use in 2018's elections and taking effect with representation in 2019.

Results of the 2018 United States House of Representatives elections in Pennsylvania:

District 1

The 1st district previously consisted of central and South Philadelphia, the City of Chester, the Philadelphia International Airport and other small sections of Delaware County. Under the new congressional map that was in place in 2019, the first district overlaps with much of the former 8th district, which is represented by Republican Congressman Brian Fitzpatrick. Fitzpatrick took office in 2017, succeeding his brother, former Congressman Mike Fitzpatrick. The new 1st district consists of Bucks County and a small portion of Montgomery County.
Fitzpatrick held out to win re-election, despite many similar suburban districts held by Republicans falling to Democrats in the 2018 cycle. Fitzpatrick did this by establishing a reputation for himself as an independent centrist who attained endorsements from several usually-left-leaning and nonpartisan groups without enraging the more fervently pro-Trump wing of the Republican party. Analysts considered the Democratic nominee Scott Wallace an unusually weak candidate: he was a wealthy heir who moved to the district, opening up accusations of carpetbagging, and made several gaffes and missteps. Editor Dave Wasserman of the Cook Political Report wrote that Wallace was perhaps the weakest candidate of the 2018 cycle.

District 2

The 2nd district consists of the northern half of Philadelphia. It mostly overlaps with the old 1st District. That district's incumbent, Democrat Bob Brady, had served since 1998, but did not run for reelection. The incumbent of the old 2nd district is Dwight Evans, but Evans opted to follow most of his constituents into the 3rd District.
The new map drew the home of fellow Democrat Brendan Boyle, who has represented the neighboring 13th District since 2015, into the 2nd, leading to speculation that he would run for reelection there. Soon after the new map was released, Boyle confirmed that he would indeed run in the 2nd.

District 3

The 3rd district was previously located in Northwestern Pennsylvania, but now covers downtown and northern Philadelphia, and overlaps with much of the previous 2nd district. The incumbent from the 2nd district is Democrat Dwight Evans, who has held office since 2016. Evans defeated incumbent Democratic representative Chaka Fattah in the 2016 Democratic primary, and then went on to be elected with 90% in both the general election and a simultaneous special election for the remainder of the term after Fattah resigned.

District 4

The old 4th district was in South Central Pennsylvania, but the new 4th district is centered in Montgomery County. The district overlaps with the former 13th district. The incumbent from this district, Democrat Brendan Boyle, could have sought re-election in either this district or the new 2nd district, which absorbed his home and most of old 13th's share of Philadelphia. Boyle opted to run in the 2nd, making the 4th an open seat.
State Senator Daylin Leach had announced that he would run for Congress in the old 7th District, but was expected to switch races after his home was drawn into the new 4th. However, on February 24, 2018, Leach succumbed to pressures from fellow Democrats, including Governor Tom Wolf, to abandon his congressional campaign in the face of accusations of sexual harassment. However, he remained in his Pennsylvania Senate seat.

The old 5th district was in North Central Pennsylvania, but the new 5th district consists of Delaware County, portions of southern Philadelphia, and a sliver of Montgomery County. The district overlaps with much of the old 7th district, whose incumbent Republican Congressman Pat Meehan chose not to seek re-election, due to allegations regarding a sexual harassment complaint that was settled with the use of taxpayer funds, and subsequently resigned from office in April.

The district overlaps with parts of the former 12th district, which is represented by Republican Keith Rothfus. Rothfus has held office since 2013, and ran for reelection in the new 17th.
The new map drew the home of Democrat Conor Lamb, who won a special election for the old 18th District, into the new 17th. The 17th is far less Republican than its predecessor, and voted for Democrats downballot, leading to speculation that Lamb would run for a full term in the 17th regardless of the special election result. On March 14, Democratic officials in Beaver County, which is entirely within the 17th, received a written request from Lamb for their endorsement in the 2018 general election. On March 20, Lamb formally filed to run for a full term in the 17th.
