Across the recorded series it reached a Democratic high of 46.9 points in 1932 and a Republican high of 55.3 points in 2024. Between 2020 and 2024 the county moved 0.6 points toward the Republican candidate; the 2024 margin was 55.3 points.
A population of 2,384, a 90% non-Hispanic-white share, and a median household income of $78,750 describe the county. The county's voting pattern over the last decade is most similar to that of Humboldt County and McHenry County.
