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.
Anchored in the Newark corridor near the University of Delaware, this district's younger, college-educated population has produced consistent double-digit Democratic presidential margins over recent cycles.
Across the recorded series it reached a Democratic high of 25.4 points in 2008 and a Republican high of 49.9 points in 1928. Between 2020 and 2024 the district moved 6.4 points toward the Republican candidate; the 2024 margin was 16.3 points.
A population of 25,130, a 63% non-Hispanic-white share, and a median household income of $79,110 describe the district. The district's voting pattern over the last decade is most similar to that of State Representative District 13 and State Representative District 24.
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.
