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.
With a 2024 presidential margin exceeding 50 points, District 66 ranks among the most skewed constituencies in the state, leaving general-election competition effectively absent and primaries as the decisive contest.
Across the recorded series it reached a Democratic high of 82.4 points in 1932 and a Republican high of 50.8 points in 2024. Between 2020 and 2024 the district moved 3.9 points toward the Republican candidate; the 2024 margin was 50.8 points.
A population of 72,803, a 78% non-Hispanic-white share, and a median household income of $83,047 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 13 and State House District 79.
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.
