Source notes · U.S. House by county, 2022 vs 2026

Tennessee: sources, checks and caveats

File: TN.csv, 95 counties. Columns: d = Democratic, r = Republican, o = all other U.S. House votes (independents and write-ins). Each county's votes are summed over every "United States House of Representatives District n" contest that includes part of it.

Sources

• 2022 (official, certified): Tennessee Secretary of State, results by precinct spreadsheet for the Nov 8, 2022 State and Federal General: https://sos-prod.tnsosgovfiles.com/s3fs-public/document/20221108AllbyPrecinct.xlsx (linked from https://sos.tn.gov/elections/results; Last-Modified Tue, 02 May 2023 19:24:11 GMT; 1,839,242 bytes; SHA-256 09fbe77438b64ecf45248da39b06fed4bcbf5be6648043867d4e57a78fac937e). Rows with OFFICENAME = "United States House of Representatives District 1..9". For each row, the RNAMEk/PARTYk/PVTALLYk columns (k = 1..10) were summed by county. PARTY "Democratic" counts as D and "Republican" as R. Everything else counts as other: "Independent", plus write-ins with a blank party, of which there was 1 vote in total.
• 2026 (unofficial): Tennessee Secretary of State Election Night Reporting dashboard, https://elections.tn.gov/ . The "County Breakdown" pages were used, one per district: https://elections.tn.gov/county-breakdown/United%20States%20House%20of%20Representatives%20District%20{1..9}. Each page lists every county in that district with candidate, party and votes. Party "Democratic" counts as D, "Republican" as R, and "Independent" as other.

2026 as-of

The Congressional page labeled races "Final Unofficial Results", e.g. "12 of 12 Counties Completed" for CD1. In every county row of all nine district breakdowns, "Precincts Completed" read x / x, with no partially reporting counties. It shows no last-updated timestamp.

Validation (sum of county rows vs statewide totals)

All columns match exactly.

Caveats

• The congressional map changed between the two elections, according to the source data. In 2022, Shelby County was split between CD8 and CD9, and Davidson County among CD5, CD6 and CD7. In the 2026 county breakdowns, Shelby is split among CD5, CD8 and CD9, and Davidson among CD4, CD6 and CD7. Many other county-to-district assignments also differ. For example, 2026 CD5 runs from Shelby and Tipton through northwest Tennessee to Maury and Williamson, and 2026 CD9 includes Bedford, Giles, Lawrence and other south-central counties. District-level comparisons between years are therefore not like-for-like. County totals sum every district touching the county, so they stay comparable.
• 2026 counts are unofficial and will change during canvass and certification.
• o = 0 means no third-party or write-in House votes were reported in that county. It does not mean the data is missing. Some 2022 districts (CD2, CD6) had only D and R candidates on the ballot.
