Josh Shapiro will probably win PA-10 comfortably this fall, but let's not forget he won it comfortably in 2022 too, by 11.8 points, and on the same ballot Scott Perry still won by 7.7. That's a 61,329 raw vote, 19.5 point Perry over-performance.
Three precinct maps of PA-10 in 2022. Governor: Shapiro won by 37,213 votes (11.8 points). Congress: Perry won by 24,116 (7.7 points). Third map: Perry ran 61,329 votes (19.5 points) ahead of the governor's race, with nearly every precinct shifting toward Perry.

馃毃Democrats have gained an excellent pickup target! This was a district that swung to the left in 2024 at the presidential level, and Trump barely won it in the first place. People like Janelle Stelson, Josh Shapiro, and John Fetterman have already shown Democrats can win here.
Three side-by-side maps of Pennsylvania鈥檚 88th State House District comparing election results. The left map shows 2020 presidential results: Joe Biden (D) with 18,082 votes (48.5%) and Donald Trump (R-Inc) with 18,655 votes (50.0%). The middle map shows 2024 presidential results: Kamala Harris (D) with 18,766 votes (48.8%) and Donald Trump (R) with 19,109 votes (49.7%). The right map shows 2024 U.S. House results: Janelle Stelson (D) with 19,494 votes (51.2%) and Scott Perry (R-Inc) with 18,560 votes (48.8%). All maps display the same district boundaries with precinct-level red and blue shading indicating partisan margins, labeled towns including Hampden, Mechanicsburg, Shiremanstown, Lower Allen, New Cumberland, and Harrisburg.

Scott Perry never struggled on this measure before, so it appears Janelle Stelson actually is a particularly strong candidate.

Might just be because Scott Perry is a weak incumbent more than anything else

See that block of blue in South Central PA? That's Janelle Stelson.

Today I鈥檓 announcing my Congressional campaign against Scott Perry. He just voted for the biggest Medicaid cuts in history, to pay for billionaire tax breaks. We deserve better than a career politician who keeps selling us out.

In 2024, according to Split Ticket, Stelson was one of the strongest Democratic candidates in the nation. If the environment in 2026 is anything close to what I expect, Perry is cooked. Not to mention it seems like Stelson did best in York, where Perry is from.

This pattern didn't really hold up as well in 2024.

When you combine Pennsylvania's 1st, 7th, and 8th congressional districts, you get a slice of PA with Philly suburbs, the Lehigh Valley, and NEPA that ends up voting almost identically to the state as a whole for a bunch of recent (and future?) elections.

Some added context for that flip last night.

With Election Night Results finished Democrat James Malone appears to have Flipped Pennsylvania's 36th Senate District after Trump won it by ~15% in 2024 the district covers around half of Lancaster County.

Presenting 2024 Senate over-performance. Blue is where Bob Casey did better. Red is where Harris did better (or another way to look at it: red is where McCormick did better). Harris actually got more votes and a higher percent than Casey, but lost by a larger % margin.
