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.
Despite Hawaii's reliably Democratic lean statewide, this state house district recorded a razor-thin D+2.4 presidential margin in 2024, making it an unusual competitive pressure point in an otherwise lopsided electoral landscape.
Across the recorded series it reached a Democratic high of 66.5 points in 1964 and a Republican high of 13.5 points in 1972. Between 2020 and 2024 the district moved 7.1 points toward the Republican candidate; the 2024 margin was 2.4 points.
A population of 34,791, a 15% non-Hispanic-white share, and a median household income of $90,180 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 36 and State House District 29.
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.
