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 East Bay, AD-6 has delivered Democratic presidential margins above 30 points in recent cycles, reflecting a dense, majority-minority electorate where turnout patterns and local races often matter more than top-of-ticket outcomes.
Across the recorded series it reached a Democratic high of 68.2 points in 1936 and a Republican high of 26.1 points in 1904. Between 2020 and 2024 the district moved 4.7 points toward the Republican candidate; the 2024 margin was 34.0 points.
A population of 516,963, a 43% non-Hispanic-white share, and a median household income of $88,541 describe the district. The district's voting pattern over the last decade is most similar to that of Assembly District 78 and Assembly District 4.
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.
