Island County's two main islands host Naval Air Station Whidbey Island, yet the county returned a Democratic presidential margin of 16 points in 2024, suggesting its substantial military-connected population does not translate into the rightward lean seen in many base counties.
Across the recorded series it reached a Democratic high of 27.2 points in 1936 and a Republican high of 57.9 points in 1904. Between 2020 and 2024 the county moved 4.5 points toward the Democratic candidate; the 2024 margin was 16.5 points.
A population of 86,836, a 75% non-Hispanic-white share, and a median household income of $90,551 describe the county. The county's voting pattern over the last decade is most similar to that of Los Alamos County and Fayette County.
