Oregon: sources, checks and caveats

File: OR.csv (36 counties). Columns: d = Democratic, r = Republican, o = all other U.S. House votes (minor-party candidates and write-ins/"Misc."). Votes summed over all six U.S. Representative districts touching each county.

Sources

• 2022 (certified): Oregon Secretary of State, November 8, 2022, General Election Abstract of Votes (PDF, pages 2–3 "US Representative" county tables), record "2022 November General Election Official Results(2)" (EPD/25/128) in the SOS records portal: https://records.sos.state.or.us/ORSOSWebDrawer/Record/13735454/File/document (record page: https://records.sos.state.or.us/ORSOSWebDrawer/Record/13735454 ; the server frequently returns truncated downloads — retry until the full 462,872-byte PDF arrives.)
• 2026 (unofficial): Oregon SOS election-night results (results.oregonvotes.gov), county breakdown service used by the "County Results" button, one call per district (raceID 300038696 … 300038701 = CD1 … CD6): https://orresultswebservices.azureedge.us/ResultsAjax.svc/GetMapData?type=FED&category=CTY&raceID=<raceID>&osn=0&county=0&party=0 Public page: https://results.oregonvotes.gov/resultsSW.aspx?type=FED&map=CTY As of: page header "Results last updated: 11/9/2026 | 6:15 PM PT" (= 9:15 pm ET Nov 9); downloaded shortly after. District totals from the county data equal the totals shown on that page.
• FIPS codes: Census national_county2020.txt.

Fusion / party lines

Oregon allows a candidate to be nominated by several parties, but the ballot lists the candidate once (e.g., "Democrat, Working Families") and votes are not split by party line — neither source reports party-line totals, only candidate totals. Therefore: - 2022: the SOS abstract labels each candidate with one party; candidate totals were assigned to that party (D/R), everyone else to o. This matches FEC exactly. - 2026: the results service reports candidate totals only with a combined party label. A candidate was counted as D or R by the first-listed party: Bonamici (CD1, "Democrat, Working Families"), Beck (CD2, "Democrat, Independent"), Hoyle (CD4, "Democrat, Working Families"), Salinas (CD6, "Democrat, Independent") → D; DeSpain (CD4, "Republican, Libertarian"), Adair (CD5, "Republican, Libertarian") → R. Their votes include any support attributable to the minor-party nomination, which cannot be separated.

Validation (sum of county rows vs statewide totals)

2022 matches exactly; each district's county rows also sum to the abstract's TOTAL line. 2026 is slightly above the aggregate because our pull (6:15 pm PT) is ~3 hours newer; Oregon (vote by mail, ballots postmarked by Election Day accepted for 7 days) is still counting.

Districts without a D or R candidate

• 2022: none — all 6 districts had both a Democratic and a Republican candidate.
• 2026: none — all 6 districts had both.

Caveats

• 2026 numbers are unofficial; the page showed statewide ballots counted 1,898,302 (61.06% turnout) at the time of download.
• 2022 o includes Progressive (Delk, CD3), Pacific Green, Independent and Constitution candidates (CD4, CD6) plus "Misc." write-ins. 2026 o includes Pacific Green/Progressive candidates (CD4 Filip, CD5 Townsend) plus write-ins.
• 2022 county cells of 0 in the abstract (e.g., CD2 rows for Clackamas, Curry, Marion) reflect that the district does not include populated parts of those counties.
• The same congressional map (enacted 2021) was in use in both years.
