Assembly District 8 delivered an 18.3-point Republican presidential margin in 2024, making it an outlier in a state where Democrats dominate the legislative map. Its inland geography and lower-density communities shape a consistently conservative electorate.
Across the recorded series it reached a Democratic high of 45.7 points in 1912 and a Republican high of 38.5 points in 1924. Between 2020 and 2024 the district moved 4.7 points toward the Republican candidate; the 2024 margin was 18.3 points.
A population of 503,696, a 49% non-Hispanic-white share, and a median household income of $92,309 describe the district. The district's voting pattern over the last decade is most similar to that of Assembly District 9 and Assembly District 3.
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.
