Across the recorded series it reached a Democratic high of 39.3 points in 1936 and a Republican high of 51.1 points in 1904. Between 2020 and 2024 the county moved 1.2 points toward the Republican candidate; the 2024 margin was 9.8 points.
A population of 423,975, a 77% non-Hispanic-white share, and a median household income of $103,517 describe the county. The county's voting pattern over the last decade is most similar to that of Clark County and Kitsap County.
