Rep. Scott Perry (R) — in Congress since 2013 and a former House Freedom Caucus chair — is defending a seat he held by just 1.26 points in 2024. Former news anchor Janelle Stelson (D) leads the challenger field and the money. PA-10 (Harrisburg–York) is an ~$80K-median-income district (5.4% uninsured).

Rated a Toss-up
Rep. Scott Perry (R) won PA-10 by just 1.26 points in 2024 (50.63%); PoliStack rates the seat a Toss-up for 2026 — one of the most competitive House races in the country.
A neck-and-neck money race
The two front-runners are within ~$280K of each other — Stelson (D) $4.69M to Perry (R) $4.42M — and Democrats lead Republicans by only ~$0.4M in total receipts. Perry leans more on small-dollar (27%) and PAC money; Stelson's haul is mostly itemized.
Markets favor the challenger
Despite Perry's incumbency, Kalshi's party-level market puts the Democratic side at 72% and the Republican side at 22% — traders price the seat to flip (figures are party-level, not candidate-specific).
