Sonoma County's blend of agricultural roots and Bay Area commuter spillover has steadily shifted its voter composition, with registration margins narrowing in some precincts even as the area trends reliably blue at the countywide level.
Across the recorded series it reached a Democratic high of 51.5 points in 2020 and a Republican high of 45.6 points in 1924. Between 2020 and 2024 the metro moved 5.3 points toward the Republican candidate; the 2024 margin was 46.2 points.
A population of 485,040, a 58% non-Hispanic-white share, and a median household income of $104,674 describe the metro. The metro's voting pattern over the last decade is most similar to that of Santa Cruz-Watsonville, CA and Napa, CA.
The metros 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.
