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.
District 51 delivered a 14.6-point Republican presidential margin in 2024, making it an outlier in a state that trends heavily Democratic statewide. Its conservative lean reflects a largely rural and small-city electorate outside the major metro corridors.
Across the recorded series it reached a Democratic high of 21.4 points in 1964 and a Republican high of 53.5 points in 1956. Between 2020 and 2024 the district moved 3.5 points toward the Republican candidate; the 2024 margin was 14.6 points.
A population of 322,945, a 82% non-Hispanic-white share, and a median household income of $70,720 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 20 and State Senate District 46.
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.
