Washington: sources, checks and caveats

View Washington counties →Download CSV All state notes

⚠ 2026 data caveat: Still counting: Washington counts mail ballots for weeks after Election Day, so 2026 totals will keep rising.

File: WA.csv (39 counties). Columns: d = candidates whose ballot party preference is "(Prefers Democratic Party)", r = "(Prefers Republican Party)", o = all other U.S. House votes (in both years these are write-ins only — every general-election race was one D-preference vs one R-preference candidate). Votes are summed over every "Congressional District n – U.S. Representative" contest in the county.

Validation (sum of county rows vs statewide totals)

Year	Column	Our sum	Reference	Diff
2022	D	1,751,582	1,751,591 (FEC)	−9
2022	R	1,261,961	1,261,966 (FEC)	−5

2026	Other	13,229 (write-ins)	(not reported)	—

2022: our county sums equal the WA SOS certified district totals exactly for all 10 districts. The −9/−5 gap vs FEC is entirely in District 3 — FEC lists Gluesenkamp Perez 160,323 / Kent 157,690, while the SOS certified export shows 160,314 / 157,685. We keep the SOS numbers.

2026: our sums also equal the source's own district summary sheet exactly. Washington votes entirely by mail and keeps counting ballots postmarked by Election Day for days afterward; the source data (5:50 pm PT Nov 9) is newer than the national aggregate (6:10 pm ET = 3:10 pm PT), which explains the higher totals. Many ballots were still uncounted when this was pulled.

Districts without a D or R candidate

2022: none — all 10 districts were D-preference vs R-preference.
2026: none — all 10 districts were D-preference vs R-preference.
No same-party (D vs D or R vs R) top-two general-election matchups in either year.

Caveats

Top-two primary state: party = candidate's stated party preference on the ballot, not a party nomination.
o is write-in votes only (WA reports write-ins as a single "WRITE-IN"/"Write-in" line).
2026 numbers are unofficial and incomplete; counties continue to tally late-arriving mail ballots until certification (Nov 24, 2026).
Same congressional map (adopted 2022) was in use in both years, so the county → district composition is comparable.

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