Across the recorded series it reached a Democratic high of 57.2 points in 1936 and a Republican high of 38.4 points in 1924. Between 2020 and 2024 the metro moved 7.1 points toward the Republican candidate; the 2024 margin was 23.0 points.
A population of 451,918, a 33% non-Hispanic-white share, and a median household income of $100,401 describe the metro. The metro's voting pattern over the last decade is most similar to that of San Francisco-Oakland-Fremont, CA and San Jose-Sunnyvale-Santa Clara, CA.
