U.S. House
Each result reflects the U.S. House district as it was drawn for that election; redistricting has redrawn these lines over time, so they can differ from the current 120th-Congress district shown on the map above.
Washington's 4th stretches across the arid Columbia Basin and Yakima Valley, where irrigated agriculture and a substantial Latino workforce shape an electorate that has returned Republican presidential margins above 20 points in recent cycles.
Across the recorded series it reached a Democratic high of 28.2 points in 1936 and a Republican high of 46.7 points in 1904. Between 2020 and 2024 the district moved 3.7 points toward the Republican candidate; the 2024 margin was 20.6 points.
A population of 768,350, a 51% non-Hispanic-white share, and a median household income of $77,137 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 20 and Congressional District 23.
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.
