Janelle Stelson holds an 80.5% implied probability in the PA-10 House race because recent polling and fundraising trends have positioned the Democrat as the frontrunner in the rematch against incumbent Republican Scott Perry. A September Franklin & Marshall poll showed Stelson ahead 47-44% among registered voters, with the economy cited as the top issue and Democrats holding a sizable edge on handling it. Stelson has outraised Perry substantially this cycle and leads among independents and moderates. Perry won the seat by just over 5,000 votes in 2024, but forecasters rate the district a toss-up or Lean Democratic. A mid-October DHS statement alleging a campaign link to an arrested individual drew a denial from Stelson with no FEC records confirming any employment tie, leaving the race dynamics largely unchanged ahead of the November 3 election.
