IA-2 · House

The district, in brief

Iowa's 2nd district is based in northeastern Iowa and contains the cities of Cedar Rapids, Waterloo and Dubuque. The facts record no redraw for this cycle; the lines are the map first used in 2022.

The seat is open. The incumbent, Republican Ashley Hinson, was re-elected with 57.1% of the vote in 2024 and is not seeking re-election, instead running for U.S. Senate. The Republican nominee is Joe Mitchell, a former state representative from the 84th district (2019–2023), who won his primary 61.5% to 38.5% over state senator Charlie McClintock; former U.S. representative Rod Blum and state representative Shannon Lundgren withdrew. The Democratic nominee is Lindsay James, state representative from the 71st district since 2019, who beat Kathy Dolter and Clint Twedt-Ball in a primary for which the text gives no vote figures; former U.S. attorney Kevin Techau withdrew and endorsed her. An independent, Dave Bushaw, appears in the fundraising tables. As of June 30, 2026 Mitchell had raised $1,938,593 with $895,564 on hand, James $1,628,201 with $755,838 on hand, and Bushaw $26,117 with $11,570 on hand.

The raters split: Decision Desk HQ (September 25, 2026) and Sabato's Crystal Ball (September 22, 2026) call it Tossup, while Inside Elections (September 17, 2026) and the Cook Political Report (June 18, 2026) have it R; Silver Bulletin is listed with an August 20, 2026 date but no ranking. Two district polls are recorded, both from Democratic firms: Global Strategy Group (July 14–19, 2026) had James 46%, Mitchell 45%, 9% undecided; Public Policy Polling, sponsored by James's campaign (April 13–14, 2026, 675 registered voters), had James 36%, Mitchell 33%, 31% undecided.

A paragraph quoting a model forecast from the day this brief was written is omitted; the current forecast is at the top of this page.

The facts, each beside its sentence

Not in the source: The Democratic primary results box is mangled; the text gives no vote counts or percentages for James's primary win.; Dave Bushaw (I) appears only in fundraising tables and not in any candidate list or the results box.; The Silver Bulletin row in the predictions table carries a date but no ranking.; The two polls are on Wikipedia but the model's basis says no district polls.; The text gives no presidential result for the district; only the facts carry a presidential baseline.; The Endorsements and Post-primary endorsements sections are empty.; facts.candidates marks no candidate as incumbent and omits Bushaw.

Who holds the seat now

Ashley Hinson (Republican), in this chamber since 2021, 3 terms. Committees: House Committee on Appropriations; House Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party; House Committee on Ethics.

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

A shift of 5.2 points toward the Republicans 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 538,235 adults 25 and over. In 2020 the district voted 47.8% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 48.5% Democratic: the midterm electorate alone moves the margin 1.4 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.

Not answered here: how each group will vote in 2026. These are 2020 preferences; this profile is description, not yet an input to the forecast.

The money

FEC bulk candidate summaries through July 13, 2026; $762,034 of independent expenditures for or against these candidates this cycle (FEC Schedule E, types 24E and 24A), which is the parties' and outside groups' own revealed view of whether this seat is in play.

The district in numbers

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.

Who is favoured, and by how much?

The 90% interval runs from -13.9 to +15.8 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: total outside/party money: 4.9 pts toward the Democrat; outside money balance: 2.2 pts toward the Democrat; asian share (1.6%): 1.4 pts toward the Republican; 2024 presidential lean (R+8.6): 1.1 pts toward the Republican; 2024 House lean (R+13.1): 0.9 pts toward the Republican.

How sure is it, and of what?

Total sd 9.05 points, made of the seat's own volatility 91%, correlated polling error 9%. 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).
