Washington's 8th stretches from the Seattle exurbs east across the Cascades, blending fast-growing suburban precincts with rural mountain communities — a mix that has kept presidential margins consistently narrow over the last three cycles.
Across the recorded series it reached a Democratic high of 6.7 points in 2020. Between 2020 and 2024 the district moved 0.9 points toward the Republican candidate; the 2024 margin was 5.8 points.
A population of 769,154, a 71% non-Hispanic-white share, and a median household income of $127,442 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 1 and Congressional District 3.
The congressional districts whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
