U.S. House
Each result reflects the U.S. House district as it was drawn for that election; redistricting has redrawn these lines over time, so they can differ from the current 120th-Congress district shown on the map above.
Hawaii's 2nd district covers the outer islands and rural Oahu, producing consistent Democratic margins above 20 points while presenting unique logistical challenges — candidates must campaign across open ocean to reach dispersed, multiethnic constituencies.
Across the recorded series it reached a Democratic high of 55.8 points in 1964 and a Republican high of 26.5 points in 1972. Between 2020 and 2024 the district moved 7.8 points toward the Republican candidate; the 2024 margin was 21.6 points.
A population of 724,712, a 28% non-Hispanic-white share, and a median household income of $95,891 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 1 and Congressional District 6.
The congressional 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.
