Connecticut: sources, checks and caveats

File: CT.csv. It covers the 8 legacy counties (09001–09015), not the 2022 planning regions. Connecticut reports by town, so the 169 town results are summed into counties. Counts are party-line only: d is votes on the Democratic Party line and r is votes on the Republican Party line. o is everything else, including Working Families and Independent Party cross-endorsement lines for D/R candidates, Green, Libertarian, and (2026 only) write-ins. Towns split between congressional districts (e.g. Glastonbury, Middletown, Waterbury, Bridgeport, Shelton) are summed across all their district parts.

Sources

• 2022 (certified): CT Secretary of the State election-history database (electionhistory.ct.gov). We used its contest CSVs with party-split columns and the City/Town rows only. Polling-place sub-rows were not used.
• District 1: https://electionhistory.ct.gov/api/download_contest/34737_table.csv?split_party=true
• District 2: https://electionhistory.ct.gov/api/download_contest/34716_table.csv?split_party=true
• District 3: https://electionhistory.ct.gov/api/download_contest/34724_table.csv?split_party=true
• District 4: https://electionhistory.ct.gov/api/download_contest/34769_table.csv?split_party=true
• District 5: https://electionhistory.ct.gov/api/download_contest/34732_table.csv?split_party=true
• Contest pages are at https://electionhistory.ct.gov/contest/.
• 2026 (unofficial): CT SOTS Election Night Reporting, https://ctemspublic.tgstg.net/ (election ID 108, "11/03/2026 -- November 2026 State Election", data version 53424). We used two files:
• Town results: https://ctemspublic.tgstg.net/ng-app/data/election/108/53424/townVotes_Electiondata.json
• Candidate, party and town lookups: https://ctemspublic.tgstg.net/ng-app/data/election/108/53424/Lookupdata.json
• Every candidate entry in the ENR is one party line, so D and R are the Democratic Party and Republican Party line entries.
• As of: file Last-Modified Tue 2026-11-10 02:27:27 GMT (Mon Nov 9, 9:27 pm ET), downloaded right after. The ENR showed 774 of 774 precincts and 169 of 169 towns reporting.
• Town→county mapping: Census 2020 county subdivision file https://www2.census.gov/geo/docs/reference/codes2020/cousub/st09_ct_cousub2020.txt, which still uses the 8 legacy counties. All 169 towns matched. The mapping was cross-checked against the ENR's own countyTowns town→county table and all 169 agree.

Validation (sum of county rows)

• 2022 matches exactly.
• The 2026 party-line sums equal the ENR's own statewide party-line totals (stateVotes file). They differ from the national aggregate by +2,173 (D) and −5,141 (R).
• the national aggregate matches neither party-line nor candidate totals exactly. The likely reason is that it was taken earlier, about 3 hours before our 9:27 pm ET snapshot, and may also mix line treatments. Candidate totals across lines are shown above for reference.

Districts with no D or no R candidate

• 2022: none. All 5 districts had both a Democratic-line and a Republican-line candidate. (The FEC's district listing suggested one district had no Republican; checked, and that does not apply to CT 2022.)
• 2026: none. All 5 districts had both.

Caveats

• Fusion votes sit in o:
• 2022: Larson (WF) 4,683; Hayes (WF) 4,020; Stevenson (Independent) 2,493; Logan (Independent) 2,492.
• 2026: Hayes (WFP) 7,353; Austin (R, also on the Independent line) 6,062.
• Write-ins: the 2022 electionhistory CSVs carry no write-in rows, so 2022 o has none. That matches the FEC "other" of 27,141. The 2026 ENR includes registered write-ins (755 votes), and they are in 2026 o.
• 2026 is unofficial. SOTS announced a discrepancy recount in Wallingford, where the town ran out of ballots and printed more. Late corrections could still change town totals.
• No UOCAVA or statewide-only rows exist in either source. All votes are attributed to towns.
