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.
Connecticut's 2nd covers the state's eastern half, blending small mill towns, farmland, and the shoreline into one of New England's larger geographic districts. Despite its rural character, it returned a D+7.8 margin in 2024.
Across the recorded series it reached a Democratic high of 37.0 points in 1964 and a Republican high of 38.5 points in 1896. Between 2020 and 2024 the district moved 3.7 points toward the Republican candidate; the 2024 margin was 7.8 points.
A population of 720,602, a 78% non-Hispanic-white share, and a median household income of $97,479 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 5 and Congressional District 3.
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.
