U.S. House
Each row is a county-allocated estimate of U.S. House votes for this district — county returns apportioned onto its boundary, not precinct-counted. “Vote lead” is the estimated local lead here, not necessarily the winner of the full contest.
Covering a swath of rural eastern Oregon, this district posts presidential margins well above 30 points, reflecting the stark political divergence between the state's sparsely populated high-desert counties and its Willamette Valley core.
Across the recorded series it reached a Democratic high of 51.6 points in 1936 and a Republican high of 45.3 points in 1904. Between 2020 and 2024 the district moved 1.1 points toward the Democratic candidate; the 2024 margin was 44.2 points.
A population of 140,700, a 76% non-Hispanic-white share, and a median household income of $129,648 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 13 and State Senate District 14.
The state-senate 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.
