ME Class 2 Senate seat

Coverage: this seat is included in the 2026 national listing.

Candidate source

Candidate source: Maine Secretary of State, Bureau of Corporations, Elections & Commissions — 2026 General Candidate List - FINAL (November 3, 2026) (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: 815 · published here: 6 · left out by rule: 809 · held back for review: 0. Official '2026 General Candidate List - FINAL' workbook, sheet 'November 3, 2026' (815 data rows, all offices). Federal rows: US Senate (statewide; Collins R, Jackson D) + CG-1 (Pingree D, Russell R) + CG-2 (Dunlap D, LePage R); districts 01/02. Senate contest is the Class II seat (Collins). Cross-checked against the SOS post-primary withdrawals/replacements PDF (9/22/2026): US Senate D nominee Graham C. Platner withdrew 7/10/2026 and was replaced by Troy D. Jackson (received 7/27/2026) - the FINAL xlsx already lists Jackson; no other federal withdrawals. Excluded rows are state/county offices (SR/SS/CC/CT/DA/JP/RP/GOV etc.). Senate rows carry senate_class=2 designation=regular: ME 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.

A poll average describes what recent surveys found. Each poll has its own sampling error, larger for smaller samples. The average is not a forecast and not a probability. Matchup: certified candidate list. 32 polls in the source were left out: party-sponsored or internal polls, other matchups, duplicate versions of the same poll, or polls missing who was surveyed.

This seat's geography is exactly coterminous with its state (or the District), so the state estimates from the same edition apply directly.

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.

“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.
