The district, in brief

Pennsylvania's 9th district is based in North Central Pennsylvania east of the Appalachian Divide. It includes Susquehanna, Bradford, Columbia, Lebanon, Montour, Northumberland, Schuylkill, Sullivan and Wyoming counties and parts of Berks, Luzerne and Lycoming, taking in Williamsport, Bloomsburg and Lebanon. The lines are the map first used in 2022 and are not redrawn for this cycle.

The incumbent is Republican Dan Meuser, re-elected with 70.5% of the vote in 2024; the facts list him as the winner in every cycle since 2018. The Democratic nominee is Rachel Wallace, a former chief of staff in the Office of Management and Budget. Both were unopposed in their primaries: Meuser took 62,527 votes and Wallace 34,503. Two Democrats withdrew before the primary: Daniel Byron, who endorsed Wallace, and Jenn Brothers, who is running as an independent write-in candidate in the general election. As of May 21, 2026 Meuser had raised $1,654,893 with $125,395 on hand, and Wallace $497,478 with $270,441 on hand.

Every rater listed calls the seat R: Decision Desk HQ (July 14, 2026), the Cook Political Report (September 11, 2025), Inside Elections (September 11, 2025), Sabato's Crystal Ball (April 10, 2025) and Silver Bulletin (August 20, 2026). A debate hosted by the Schuylkill County Chamber of Commerce is scheduled for October 20, 2026, with both candidates invited. No district polls are recorded.

Who holds the seat now

Daniel Meuser (Republican), in this chamber since 2019, 4 terms. Committees: House Committee on Financial Services; House Committee on Small Business.

From the congress-legislators dataset (CC0), archived as ae8cb9477c48. For a Senate race this lists both of the state's senators; the one whose term ends in the election year holds the seat on the ballot. For a House district redrawn for 2026 it is the member elected under the old lines with this number, who may be running elsewhere; the dossier above names who is running here.

How it has voted for president

Two-party margin201620202024
PresidentR+38.2R+34.4R+35.9

A shift of 2.3 points toward the Democrats from 2016 to 2024. county returns placed on the current lines by 2020 block population; MEDSL county file (2016), an MIT-licensed county file (2020, checked against certified state results) and MEDSL precinct returns (2024). For a district split across counties this is an estimate, and where the state published the exact 2024 figure for these lines, that exact figure is the one the model uses.

Who are the voters?

Of about 544,856 adults 25 and over. In 2020 the district voted 31.5% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 32.5% Democratic: the midterm electorate alone moves the margin 2.0 points toward Democrats. Group shares are estimated from how results vary across the state's census tracts (ecological inference, anchored to Pew's 2020 validated-voter figures) and calibrated to this district's actual 2020 vote; turnout is the Census survey's state rate by race and national rate by education, whose state samples carry margins of several points.

ACS 5-year 2023, the Census Bureau's own tabulation of this district (118th Congress lines). Unemployment is the BLS county series placed on the district by block population, not seasonally adjusted, so changes are same-month comparisons. Income, transfers and jobs are BEA county accounts placed the same way, compared with the average district. Every other figure is a named column of a named table in the Bureau's summary file, archived before it was read. This is what a reader knows about a district before looking at a poll; the model does not yet use it, and whether it should is a registered question.

The 90% interval runs from -44.0 to -16.3 points, D-R. It is wide because this district has never been polled.

What is this built on?

A model trained on every contested House race 2012-2024 predicts this district's lean from its own record: presidential and House results on the current lines, incumbency, both candidates' prior offices, outside and party money before 1 October, demographics and public-assistance shares from the Census release before the election, local unemployment and income, and religious tradition. The national margin comes from presidential approval, the economy, the midterm penalty and the generic ballot corrected for its measured lean. Draws share national and state errors, so the seat total and this district come from the same simulation.

Not answered here: district polls, which are not yet folded in.

Why does the model say this?

Each figure is how far this district's predicted lean moves when that one feature is set to the typical value across 2026 districts, everything else held: 2024 presidential lean (R+36.8): 17.9 pts toward the Republican; 2024 House lean (R+38.3): 8.8 pts toward the Republican; religion: mainline (15.0%): 1.0 pts toward the Democrat; PAC money balance: 0.7 pts toward the Republican; experience gap (-4 levels, D minus R): 0.6 pts toward the Republican.

How sure is it, and of what?

Total sd 8.42 points, made of the seat's own volatility 89%, correlated polling error 11%. The decomposition is stored with the forecast rather than reconstructed, so a probability whose dominant input is a placeholder is visibly that.

Not answered here: a nowcast. 'If ballots were cast today' needs something that observes today, and for a House district nothing does. Publishing the election-day figure under both labels would make one forecast look like two.

How was this number made?

Run 6f211e6f-2bdc-4dda-8f72-81fc628dab0b, house_district_prior/0.2.0, as of 2026-10-02. Promoted by a pre-registered gate: on 2016-2022 its Brier score was 0.036 against 0.049 for the previous method, and on a single 2024 run 0.023 against 0.032 (experiments/district_gate_result.md, with an independent review).
