Massachusetts: sources, checks and caveats
⚠ 2026 data caveat: Partial 2026 count: in MA-2, MA-5 and MA-7 (no Republican candidate) the AP feed stopped updating at 62–89% of expected votes, so Democratic votes in those districts are undercounted.
File: MA.csv (14 counties). Massachusetts reports by city/town: 351 municipalities. Cities and towns split between districts (e.g. Boston, Cambridge, Brockton, Fall River) appear once per district part and are summed: 360 town-district rows in 2022 and 360 AP units in 2026. d is the Democratic candidate, r the Republican, and o all other candidates plus "All Others" (write-ins) where reported. Blanks are excluded.

- 2026 (unofficial): the state does not publish unofficial town results; electionstats has no 2026 general yet. We used Associated Press town-level results, as embedded on WBUR's results page https://www.wbur.org/news/2026/11/03/massachusetts-2026-election-results-us-house-congress. The AP data are at:
https://interactives.apelections.org/election-results/data-live/2026-11-03/results/races/MA/20261103<RACE>/detail.json plus metadata.json for parties.- Race IDs: D1 MA22947, D2 MA22948, D3 MA22949, D4 MA22950, D5 MA24356, D6 MA22952, D7 MA22953, D8 MA22954, D9 MA23865.
- The AP CDN refuses plain curl, so the files were fetched and summed in a browser page on that host.
- As of: AP
lastUpdated per race is between 2026-11-09T15:10Z and 19:37Z (10:10 am–2:37 pm ET); latest is 19:37:39Z. Read about 6:15 pm ET Nov 9.
- Town→county mapping:
- 2022: by town name, using Census 2020 county subdivisions (https://www2.census.gov/geo/docs/reference/codes2020/cousub/st25_ma_cousub2020.txt). Abbreviations such as "E. Bridgewater" and "N. Attleborough" were expanded; "Town city" names such as Braintree and Watertown were handled. All 360 rows matched.
- 2026: by AP's Census town FIPS code, looked up in the same file. Four AP codes are not in the 2020 list because those places were renamed "Town city": Easthampton 19365, Methuen 40675, Watertown 73405, Amesbury 01185. For these, AP's county was used (Hampshire, Essex, Middlesex, Essex), which matches the Census entries for those towns.

Both years match exactly; the 2026 reference evidently comes from the same AP feed.
Districts with no D or no R candidate
- 2022: D4 had no Republican (Auchincloss unopposed; "All Others" 6,397). All districts had a Democrat.
- 2026: D1 (Neal vs. Milleron, Independent), D2 (McGovern only), D5 (Clark only) and D7 (Pressley only) had no Republican. All districts had a Democrat. In those districts' towns
r26 is 0, not imputed. This is why Berkshire, Franklin, Hampden and Hampshire show r26 = 0.
Caveats
- 2026 uncontested districts are incomplete in AP's feed. AP's expected-vote share was 63% for D2, 89% for D5 and 62% for D7, against 99% for every contested district. AP evidently stopped updating these single-candidate races (last updates 15:10–15:22Z Nov 9). The D votes for towns in D2, D5 and D7 (Worcester, Middlesex, Suffolk and others) are therefore undercounts, not final. No other 2026 town-level source was available as of Nov 9.
- 2026
o = Milleron (Ind, D1) 93,786; Conlon (Unenrolled, D3) 6,442; Walters (Ind, D8) 10,579. AP reports no write-ins, while 2022 o includes "All Others" (write-ins) plus Tashjian (Unenrolled, D6).
- No UOCAVA or statewide-only rows. MA counts these in the voter's town.
