Maine: sources, checks and caveats

File: ME.csv (16 counties). Maine reports by municipality, plantation and unorganized territory, and these are summed into counties. Maine uses ranked-choice voting, and first-round (first-choice) votes are used. d is the Democratic candidate, r the Republican, and o all other candidates plus write-ins. Blank votes are excluded. Unorganized territories are included in their county: in the 2022 SOS files each UT row carries its county code, and AP reports UTs as separate units with Census FIPS.

Sources

• 2022 (certified): Maine Secretary of State, 2022 election results page https://www.maine.gov/sos/elections-voting/election-results-data/2022-election-results (November 8, 2022 section). Two files were used:
• CD1 (no RCV tabulation needed): https://www.maine.gov/sos/sites/maine.gov.sos/files/inline-files/Rep%20to%20Congress%20Dist.%201.xlsx
• CD2, RCV central count first choice by town: https://www.maine.gov/sos/sites/maine.gov.sos/files/inline-files/CG%202%20First%20Choice%20Results.xlsx
• The SOS's own CTY column gives each town's county.
• maine.gov returns HTTP 403 to curl, so the XLSX files were read in a browser page on maine.gov and summed there by the CTY column.
• 2026 (unofficial): the Maine SOS had not posted 2026 general results as of Nov 9; its results page lists only the June 2026 primary. We used Associated Press town-level results from AP's public results feed (the same AP interactives feed used by news-site results pages):
• CD1: https://interactives.apelections.org/election-results/data-live/2026-11-03/results/races/ME/20261103ME20644/detail.json
• CD2: https://interactives.apelections.org/election-results/data-live/2026-11-03/results/races/ME/20261103ME20645/detail.json
• Party labels come from metadata.json. The files were fetched and summed in a browser page on the AP host, because the CDN refuses curl.
• As of: AP lastUpdated 2026-11-09T22:05:35Z for CD1 and 22:25:45Z for CD2 (5:05 / 5:25 pm ET), read about 6:20 pm ET.
• Only town-level units were summed (reportingunitLevel 2, 520 units); AP's 83 sub-town units were excluded. County comes from AP's Census town FIPS code, checked against Census 2020 county subdivisions (https://www2.census.gov/geo/docs/reference/codes2020/cousub/st23_me_cousub2020.txt).
• All units matched except: "Drew unorganized territory" (code 18582, not in the 2020 list), which was put in AP's county, Penobscot; and "Overseas Absentee" (see below).

Validation (sum of county rows)

• UOCAVA / overseas votes cannot be assigned to a county and are excluded from the county rows:
• 2022 "STATE UOCAVA" rows: CD1 D 951 / R 91 / other 1; CD2 D 617 / R 117 / other 69. Total D 1,568, R 208, O 70.
• 2026 AP "Overseas Absentee" units: D 4,452, R 387, other 0 (blank 8).
• With these added back, 2026 matches the national aggregate exactly.
• 2022 vs FEC: the SOS spreadsheets total D −51, R −55, other −473 relative to FEC. The CD2 file is the RCV central-count first-choice tabulation, and FEC's figures appear to come from a slightly different tabulation. The "other" gap is probably CD2 write-ins, which have no column in the first-choice file. This was not confirmed. The CD1 file total (Pingree 219,753 / Thelander 129,263 / others 160) and the CD2 file total (Golden 153,023 / Poliquin 141,205 / Bond 21,575) were used as published.

Districts with no D or no R candidate

• 2022: none (CD1 Pingree D / Thelander R; CD2 Golden D / Poliquin R / Bond Ind).
• 2026: none (CD1 Pingree D / Russell R; CD2 Dunlap D / LePage R; write-in Ward).

Caveats

• o is not comparable across years: 2022 includes Bond (Independent, CD2) 21,575. In 2026 the only non-D/R entries are CD2 write-ins (Ward, 125). AP shows no other candidates for CD1.
• Blank votes excluded: 2022 had 8,962 in CD1 and 6,968 in CD2; 2026 CD2 had 6,021. AP's CD1 2026 feed has no blank line.
• 2026 is unofficial. AP's CD2 expected-vote share was 97.8%, and CD2 may still be reviewed or tabulated under RCV rules. First-choice counts are reported here.

These notes record where each number came from and how it was checked. 2026 figures are unofficial. See the methodology and disclaimer.
