Pennsylvania's Four House Races Will Tell Us Whether Democrats Win Big or Barely

With mail-in ballots already going out and more than $105 million in advertising flooding screens across the state, Pennsylvania has become the country's most watched laboratory for what happens when a president's approval rating collapses — and whether that collapse is enough to flip Congress.

Four House districts — PA-1, PA-7, PA-8, and PA-10 — are the ones to watch on November 3. Democrats need to flip the House, and strategists in both parties say Pennsylvania's quartet of battlegrounds will reveal whether that flip is a wave or a squeaker. A sweep of all four would signal a Democratic wave; losing all four would represent an unexpected Republican revival.

The backdrop is a sharp reversal from two years ago. Pennsylvania served as the center of a Republican resurgence in 2024: Trump won the state's electoral votes, Republicans unseated a long-incumbent Democratic senator, and Pennsylvania stood alone as the state where the party picked up two House seats. The most recent Times/Inquirer/Siena poll now shows Trump's Pennsylvania approval rating has dropped to 34 percent, with three-quarters of voters giving him poor marks on his handling of the cost of living.

The Cook Political Report rates the four districts as follows: PA-1 (Brian Fitzpatrick vs. Bob Harvie) leans Republican; PA-7 (Ryan McKenzie vs. Bob Brooks) leans Democratic; PA-8 (Rob Bresnahan vs. Paige Cognetti) is a toss-up; and PA-10 (Scott Perry vs. Janelle Stelson) leans Democratic, according to Patch.

Each race maps onto a distinct national dynamic. In suburbs that have otherwise shifted toward Democrats, one Republican is fighting to hold on. Hispanic communities that grew rapidly and moved rightward in 2024 are now Democratic targets. In aging industrial towns and rural stretches, white working-class voters have grown disillusioned with the president's pledges. The contests feature the House's most vocal moderate Republican and the former chairman of the hard-right House Freedom Caucus, respectively. Campaign ads are repeatedly raising stock trading and corruption, while charges of socialism are being hurled in the other direction.

PA-1: The race that should be easiest on paper — and isn't. The district on the outskirts of Philadelphia voted against Trump in 2016, 2020, and 2024. Even so, Representative Brian Fitzpatrick, a moderate Republican, prevailed each time — making him the sole member of his party to win a district that rejected Trump in all three elections. He counts support from labor unions and some major environmental groups, organizations that typically back Democrats. His challenger, Bob Harvie, is banking on the 60 percent approval rating of Democratic Governor Josh Shapiro to carry him over the line.

All of us who are running are going to be clutching both hands, white knuckles, onto those Josh Shapiro coattails. Because they're going to take us somewhere.— Bob Harvie, Democratic challenger, PA-1

Shapiro has endorsed Harvie and appeared with him on two consecutive weekends — but notably did not mention Fitzpatrick by name at either event, instead speaking narrowly about congressional control. Without endorsing the Republican gubernatorial candidate, Fitzpatrick described Shapiro as a "friend" and said he had extended a wedding invitation to him over the summer, an invitation Shapiro did not accept. Democrats at the national level have since incorporated images of Fitzpatrick in black tie at his wedding reception into attack advertisements.

Not a coincidence.— Brian Fitzpatrick, Republican incumbent, PA-1

Both parties' national leaders have treated Pennsylvania as a must-visit. Representative Hakeem Jeffries, the Democratic leader, launched his 100-day sprint to the speakership in Pennsylvania over the summer, then returned last weekend for a rally in one district and appearances in Black churches in another. Speaker Mike Johnson, whose job Jeffries is trying to take, blitzed through all four Republican-held battlegrounds in a single day.

Beyond Congress, Pennsylvania's state legislative chambers are also in play. Democrats have held a narrow majority in the 203-seat state House since 2022, currently 103 to 100. They are also targeting the state Senate, where they trail Republicans 27 to 23 — a chamber Democrats have not controlled since the early 1990s. The governor's race pits incumbent Democrat Josh Shapiro against Republican Treasurer Stacy Garrity.

One issue has scrambled the usual partisan lines in ways that could affect multiple races: artificial intelligence data centers. An unlikely coalition has pushed back against Shapiro's strong backing of data center construction, which includes a full state tax exemption for such facilities that Food and Water Watch says could deprive Pennsylvanians of $2 billion in revenue by 2031. Democratic State Senator Katie Muth and leading Republicans, including Garrity and State Senator Rosemary Brown, are calling for a statewide moratorium on all data center construction. Documents obtained by Concerned Citizens of Montour County reveal that Shapiro's administration maintained close contact with major data center developers and Amazon, with those communications touching on how and when to make announcements public and on efforts to keep Amazon's role in major state projects from becoming known.

For voters still deciding how to participate: mail-in ballots are available to all Pennsylvania voters. The deadline to request one is 5 p.m. on October 27. Completed ballots must be returned to a designated drop-off location by 8 p.m. on November 4. Voters who arrive at a polling place in person are not required to show photo identification unless they have never voted at that precinct before, according to Pennsylvania law and the Secretary of State's office.

Voting by mail is a convenient, safe, and secure option for eligible Pennsylvanians. Those who prefer to vote by mail should apply today to ensure they have time to receive, mark, and return their ballot by Election Day.— Al Schmidt, Pennsylvania Secretary of State

Why it matters — Pennsylvania's four competitive House seats will function as a real-time gauge of whether economic discontent with Trump translates into a Democratic House majority — or whether Republican incumbents can survive the backlash.
