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.^{[1] [2]}

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 to 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.^[3]

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 (represented per 2018's elections), the first district overlaps with much of the former 8th district, which was represented by Republican Representative Brian Fitzpatrick. Fitzpatrick took office in 2017, succeeding his brother, former Representative Mike Fitzpatrick. The new 1st district consists of Bucks County and a small portion of Montgomery County.^[7]

The Wallace campaign responded with an ad higlishting Reddick flubbing a question about the so-called “global gag rule” during a campaign stop in Ottsville,^[15] and for her having been registered as a Republican for most of her adult life.^[16]

Many DC Democrats expressed excitement about Wallace's potential to spend big to defeat Fitzpatrick, especially in the expensive Philadelphia market. He loaned his campaign $2.5 million while Reddick only raised $363,000 and was shunned by most party strategists.^[17]

Analysis

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.^[33]

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.^[7]

The new map drew the home of fellow Democrat Brendan Boyle, who had 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.^[34]

Democratic primary

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.^[36]
