Key Facts — Pennsylvania
What Pennsylvania's Swing Means for 2026 Voters
Pennsylvania's 2024 results reshaped the national political map. Trump's 4.5-point win in a state Biden had carried just four years earlier confirmed a lasting realignment: the working-class Rust Belt corridor — Scranton, Allentown, Reading — has moved structurally toward Republicans, while Philadelphia's suburbs remain competitive but no longer enough to offset rural losses.
For 2026, this has three major implications:
- Governor race (2026): Josh Shapiro cannot seek a third term in 2026 (he is in his first term but is widely expected to pursue other offices). Pennsylvania will have an open governor race for the first time since 2022. Republicans, energized by the 2024 presidential result, will contest it aggressively.
- Economic issues dominate: Pennsylvania has a large manufacturing base (steel, chemicals, natural gas) and a significant rural healthcare network. Trump's tariffs, Medicaid policy, and manufacturing jobs will all be central to how Pennsylvania voters evaluate the 2026 choices.
- The suburban battleground: Chester, Bucks, Montgomery, and Delaware counties in the Philadelphia suburbs remain the key swing terrain. Democrats need to hold or grow margins there to remain competitive statewide. The Democratic coalition that elected Fetterman in 2022 — Philadelphia base plus suburban swing voters — needs to hold together.

Frequently Asked Questions
How did Pennsylvania vote in the 2024 presidential election?
Pennsylvania voted for Donald Trump in 2024, with Trump receiving 51.8% versus Harris's 47.3% — a margin of 4.5 points. It was a significant swing from 2020, when Biden carried the state by 1.2 points. The 5.7-point shift toward Republicans was one of the largest of any major swing state.
Who are Pennsylvania's current US senators?
Pennsylvania's two US senators are Dave McCormick (R), who won the 2024 race by defeating three-term incumbent Bob Casey, and John Fetterman (D), who won in 2022 in a nationally watched race against Dr. Mehmet Oz. McCormick is a hedge fund executive; Fetterman is a former Braddock mayor known for blue-collar Democratic politics.
What is Pennsylvania's political lean in 2026?
Pennsylvania is a genuine Toss-up. Josh Shapiro won the governorship in 2022 by 14 points in the same cycle Democrats lost the Senate race. Trump won the state in 2016 and 2024 but lost it in 2020. No simple label captures the ticket-splitting nature of Pennsylvania's electorate.
What does Pennsylvania's 2024 swing mean for 2026?
The 5.7-point swing toward Trump from 2020 to 2024 signals that working-class Rust Belt voters in cities like Scranton, Allentown, and Reading have shifted structurally toward Republicans. Democrats must offset these losses with suburban margins. The 2026 governor race will be the first real test of whether the 2024 shift was durable or driven by candidate-specific factors.
Is there a Pennsylvania Senate race in 2026?
No. Dave McCormick just won his Senate seat in 2024 and is not up for reelection until 2030. John Fetterman's seat comes up in 2028. The major 2026 contest in Pennsylvania is the governor's race.
