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.
Maryland's 6th stretches from the Appalachian panhandle through fast-growing Montgomery County suburbs, a geographic mix that shifted the district's partisan lean sharply after court-ordered remapping in the 2010s.
Across the recorded series it reached a Democratic high of 23.5 points in 1912 and a Republican high of 34.6 points in 1928. Between 2020 and 2024 the district moved 4.0 points toward the Republican candidate; the 2024 margin was 5.7 points.
A population of 777,860, a 60% non-Hispanic-white share, and a median household income of $102,585 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 3 and Congressional District 10.
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.
