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.
Spanning the Chesapeake's Eastern Shore and stretching into rural Western Maryland, the district recorded an R+16.8 presidential margin in 2024 — the widest Republican spread in a state that otherwise votes heavily Democratic at the federal level.
Across the recorded series it reached a Democratic high of 13.1 points in 1932 and a Republican high of 50.0 points in 1972. Between 2020 and 2024 the district moved 2.4 points toward the Republican candidate; the 2024 margin was 16.8 points.
A population of 772,217, a 72% non-Hispanic-white share, and a median household income of $94,639 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 4 and Congressional District 1.
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.
