The district, in brief
Colorado's 6th district takes in much of the eastern Denver metropolitan area, as well as parts of the southern and northern area. The lines are not redrawn for 2026; the facts record the map as first used in 2022. The text gives no presidential results, but the facts carry a 2024 presidential baseline on the current lines.
The incumbent is Democrat Jason Crow, re-elected with 59% of the vote in 2024 and unopposed in the Democratic primary with 94,207 votes after two candidates withdrew. The Republican nominee is Jason Clark, for whom the text gives no background; he was unopposed in the Republican primary with 38,437 votes after Mel Tewahade, described as the original nominee, withdrew. Independents Edwardo Quinonez and Samir Witta filed paperwork. As of June 30, 2026 Crow had raised $3,177,447, spent $2,217,842 and held $2,707,899; Clark reported $0 raised, spent and on hand.
Every rater listed calls the seat D: Decision Desk HQ (July 14, 2026), the Cook Political Report (February 6, 2025), Inside Elections (March 7, 2025), Sabato's Crystal Ball (April 10, 2025) and The Economist (May 6, 2026). The text records no district polls and names no endorsements.

Who holds the seat now
Jason Crow (Democrat), in this chamber since 2019, 4 terms. Committees: House Committee on Armed Services; House Permanent Select Committee on Intelligence.
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 margin | 2016 | 2020 | 2024 |
|---|---|---|---|
| President | D+14.3 | D+24.1 | D+19.9 |
A shift of 5.6 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?
| Group (adults 25+) | Share of adults | Turnout 2020 / midterm | Share of a midterm electorate | Est. Democratic share, 2020 |
|---|---|---|---|---|
| White, no degree | 30% | 60% / 52% | 28% | 28% |
| White, degree | 34% | 82% / 80% | 48% | 76% |
| Black | 10% | 52% / 28% | 5% | 93% |
| Hispanic | 17% | 37% / 36% | 11% | 69% |
| Asian | 6% | 33% / 48% | 5% | 72% |
| Other / multiracial | 4% | 63% / 59% | 4% | 67% |
Of about 495,771 adults 25 and over. In 2020 the district voted 62.2% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 62.5% Democratic: the midterm electorate alone moves the margin 0.6 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.

FEC bulk candidate summaries through June 30, 2026; no independent expenditures reported for or against any candidate, which usually means nobody outside the district thinks it is in play.

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 +17.6 to +45.2 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 (D+21.9): 16.5 pts toward the Democrat; 2024 House lean (D+23.8): 8.9 pts toward the Democrat; PAC money balance: 7.4 pts toward the Democrat; experience gap (+4 levels, D minus R): 7.0 pts toward the Democrat; Democrat's experience (incumbent): 1.4 pts toward the Republican.
How sure is it, and of what?
Total sd 8.41 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).
