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.
Covering parts of Sussex and Warren counties, this rural and small-town district backed the Republican presidential nominee by 3 points in 2024 — a narrower gap than its historical baseline suggests, signaling a gradually shifting electorate.
Across the recorded series it reached a Democratic high of 34.5 points in 1964 and a Republican high of 52.9 points in 1928. Between 2020 and 2024 the district moved 7.0 points toward the Republican candidate; the 2024 margin was 10.7 points.
A population of 236,448, a 58% non-Hispanic-white share, and a median household income of $76,889 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 2 and State Senate District 40.
