Colorado's 1st congressional district
Coverage: this seat is included in the 2026 national listing. State candidate coverage class: candidate coverage verified from the state's official list. Absence of candidate rows is not evidence that a race has no candidates — see the coverage ledger.
Candidate source
Candidate source: Colorado Secretary of State — 2026 General Election Official Candidate List (retrieved 2026-09-28). Absence of a candidate row is never evidence that a race has no candidates.
How the candidate list was checked
Rows read from the official source: 404 · published here: 47 · left out by rule: 357 · held back for review: 0. Official 2026 General Election Official Candidate List table. All 8 House districts (01-08) present: 01,02,03,04,05,06,07,08. 9 US Senate candidates (incl. 3 certified write-ins: Donald Willoughby, Will Powers, Ryan Apelbaum). Excluded rows are state/local offices (State House 135, State Senate 46, judicial, RTD, Regents, etc.). Party listed as printed; write-in rows carry status write_in. [Re-fetched same URL later on 2026-09-28 after incidental deletion; page bytes differ upstream (page self-updates) but all 47 federal rows re-parsed byte-identical: 47/47 match, zero add/remove. raw_sha256 and manifest updated to the re-fetched bytes.] Senate rows carry senate_class=2 designation=regular: CO is in the official Senate Class II registry (the state's only scheduled 2026 Senate race), so the seat identity is derived from the registry, not defaulted.

Census block equivalency files show this state's 119th- and 120th-Congress representations are block-identical, so the 119th-Congress ACS district product binds exactly to this district.
Structural five-year survey conditions — not current monthly conditions. Uncertainties are 90% margins of error: the published ACS margin for median income; Census-formula approximations (ACS handbook ch. 8) for the rates. “Margin unavailable” means the source supplies no usable margin — never zero.
Campaign finances
2025-2026 two-year period (FEC cycle 2026). Committee totals are the FEC’s own candidate-level aggregation — never summed from committee rows here. Independent spending is reported separately and is never part of a candidate’s receipts. An FEC registration is not proof of ballot qualification; candidacy status comes verbatim from the accepted release.
General election · November 3, 2026
“No matching FEC candidate record” means no filing was located — it is never evidence that a candidacy does not exist, and never a ballot-status claim. Candidates’ coverage dates can differ; each row carries its own.
