Presidential Results — Pennsylvania 2016–2024
Pennsylvania has flipped twice in three cycles. Trump won by 0.7 in 2016, Biden recaptured it by 1.2 in 2020, and Trump won it back by 4.5 in 2024 — a significant structural rightward shift driven by non-college working-class voters in the northeast and rural counties.

The House Majority Runs Through Pennsylvania
Pennsylvania is home to three of the most closely watched House districts in the country. Democrats need a net gain of five seats nationally — tracked on the House 2026 forecast page — to retake the House majority from Republicans. Democrats need a net gain of five seats nationally to retake the House majority from Republicans. PA-1 (Bucks County) and PA-7 (Montgomery County) represent the battleground of the Philadelphia suburban corridor — a region where independent voter trends and generic ballot movement directly shape outcomes — one of the most demographically dynamic regions in American politics, where college-educated white voters have moved sharply toward Democrats over the past decade while Trump has consolidated working-class support elsewhere in the state. Winning both would put Democrats a significant step toward the majority.
The Northeast Pennsylvania Question
PA-8, covering Scranton, Lackawanna County, and Luzerne County, is the district that best captures Pennsylvania's transformation. This was working-class Democratic turf for decades — Scranton is Joe Biden's hometown — but has shifted decisively toward Trump. Rob Bresnahan won the seat in 2024 by 5 points in a district Trump carried by double digits at the presidential level. Democrats face a structural disadvantage here: the working-class voters who once made this district reliably blue have not returned to the party in any recent cycle. The district is rated Lean R, but a strong Democratic environment in 2026 could put it in play.
Shapiro and the Governor's Race
Josh Shapiro is one of the most popular governors in the country. His re-election race is rated Likely D, and his coattails in the Philadelphia suburbs could help competitive House 2026 candidates. He won in 2022 by 14 points in a competitive state, has maintained approval ratings above 55% across partisan lines, and has carefully cultivated an image as a results-focused pragmatist. His re-election in 2026 is not seriously in doubt. The question is whether Shapiro, if he runs for governor rather than higher office, can pull up Democrats in the competitive House districts on the same ballot. His coattails in the Philadelphia suburbs in particular could be valuable to Democratic House candidates in PA-1 and PA-7.
Key Dynamics
Philadelphia's collar counties — Bucks, Montgomery, Chester, Delaware — have shifted dramatically toward Democrats since 2016. College-educated suburban voters, especially women, are now a core Democratic constituency in a region Republicans once dominated. PA-1 and PA-7 sit in this terrain.
Non-college white voters in northeast PA, the Lehigh Valley, and across western Pennsylvania have moved sharply toward Republicans. Trump's 4.5-point 2024 win reflected sustained erosion among this group that Democrats have not reversed. PA-8 is the emblematic district.
Midterm elections historically favor the party out of the White House — see midterm wave history 1994–2018. The Trump approval tracker is the key variable for the size of any Democratic wave in 2026. With Trump in office, Democrats will benefit from a structural tailwind in competitive districts. Whether that tailwind is strong enough to flip PA-1 and PA-7 depends heavily on economic conditions and Trump's approval rating by fall 2026.
