The2018 United States House of Representatives elections in Pennsylvania were held on November 6, 2018, to elect the 18U.S. representatives from theCommonwealth of Pennsylvania, one from each of the state's 18congressional districts.

The elections coincided with the2018 gubernatorial election, as well asother elections to the House of Representatives,elections to theUnited States Senate, and variousstate and local elections.

In January 2018, thePennsylvania Supreme Courtstruck down the state's congressional map, ruling it had been unfairlygerrymandered to favorRepublicans. 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]

U.S. Representative before election Brian Fitzpatrick (8th) Republican Elected U.S. Representative Brian Fitzpatrick Republican

The 1st district previously consisted of central andSouth Philadelphia, theCity of Chester, thePhiladelphia International Airport and other small sections ofDelaware County.^[7] 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 RepresentativeBrian Fitzpatrick. Fitzpatrick took office in 2017, succeeding his brother, former RepresentativeMike Fitzpatrick. The new 1st district consists of Bucks County and a small portion of Montgomery County.^[7]

• Brian Fitzpatrick, incumbent U.S. representative

• Dean Malik, formerBucks County assistant district attorney and candidate for this seat in2010 &2016^[8]

• Valerie Mihalek, former Yardley Borough council member and deputy district director for former U.S. Rep. Mike Fitzpatrick^[9]

The old 8th district was included on the initial list of Republican held seats being targeted by theDemocratic Congressional Campaign Committee.^[10]

• Scott Wallace, charitable foundation director and grandson of former Vice PresidentHenry Wallace^[11]

• Steven Bacher, environmentalist^[12]
• Rachel Reddick, former Navy prosecutor^[13]

• Diane Ellis-Marseglia, Bucks County commissioner^[14]

The race featured a number of negative ads between Reddick and Wallace. With Reddick's campaign releasing an ad calling Wallace a “Maryland multi-millionaire” and stating that he had case an absentee ballot cast from his second home in a South African “gated luxury estate”. 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]

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 ofcarpetbagging, and made several gaffes and missteps. Editor Dave Wasserman of theCook Political Report wrote that Wallace was perhaps the weakest candidate of the 2018 cycle.^[60]
