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 sparsely populated high-desert and agricultural terrain, this district backed the 2024 Republican presidential nominee by nearly 14 points, reflecting a broader rural realignment that has reshaped Oregon's political map outside the Willamette Valley.
Across the recorded series it reached a Democratic high of 43.8 points in 1964 and a Republican high of 42.1 points in 1904. Between 2020 and 2024 the district moved 1.3 points toward the Democratic candidate; the 2024 margin was 8.2 points.
A population of 70,194, a 83% non-Hispanic-white share, and a median household income of $65,612 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 12 and State House District 1.
The state-house 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.
