The district, in brief

Indiana's 2nd district lies in north central Indiana and takes in Michiana, including South Bend, Mishawaka, Elkhart and Warsaw. The lines are the map first used in 2022; the district was not redrawn for this cycle.

The incumbent is Republican Rudy Yakym, re-elected with 62.7% of the vote in 2024 and unopposed in his primary with 41,228 votes. The Democratic nominee is Jamee Decio, an attorney, who won her primary 72.1% to 27.9% over middle school teacher Shaun Maeyens. Libertarian William Henry, the party's 2024 nominee, was nominated at convention. As of June 30, 2026 Yakym had raised $5,246,030 and spent $5,000,296, with $855,313 on hand; Decio had raised $355,589 with $104,496 on hand; Henry reports $0.

Every rater with a call listed rates the seat R: Decision Desk HQ (July 14, 2026), the Cook Political Report (February 6, 2025), Inside Elections (March 7, 2025) and Sabato's Crystal Ball (July 15, 2025). Silver Bulletin appears in the table dated August 20, 2026 with no rating shown. The text records no general-election poll and no presidential result.

Not in the source: The facts have no presidential baseline for this district (null) and the text gives no presidential result.; Silver Bulletin's row in the ratings table has a date but no rating.; William Henry (Libertarian) is on the ballot in the text but not in the facts' candidate list.; No general-election polls are listed, consistent with the model's basis of no district polls.; Ratings are given only as 'R' with no Lean/Likely/Safe gradation; no endorsements are listed.

Who holds the seat now

Rudy Yakym III (Republican), in this chamber since 2022, 3 terms. Committees: House Committee on Ways and Means.

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+25.5R+21.8R+18.3

A shift of 7.2 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 495,004 adults 25 and over. In 2020 the district voted 38.5% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 38.3% Democratic: the midterm electorate alone moves the margin 0.5 points toward Republicans. 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 -33.2 to -5.5 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+25.0): 8.6 pts toward the Republican; 2024 House lean (R+26.2): 5.3 pts toward the Republican; asian share (1.5%): 1.8 pts toward the Republican; experience gap (-4 levels, D minus R): 1.5 pts toward the Republican; pc income growth 2y (5.37): 0.9 pts toward the Republican.

How sure is it, and of what?

Total sd 8.43 points, made of the seat's own volatility 90%, correlated polling error 10%. 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).
