Migration is one input to a place’s political change, not its cause — a shift can also come from residents changing their minds, generational turnover, or turnout. These figures describe the places people moved between; they do not measure how any mover voted.

Across the recorded series it reached a Democratic high of 20.7 points in 1936 and a Republican high of 53.7 points in 1984. The 2024 margin was 6.8 points.
A population of 12,425, a 79% non-Hispanic-white share, and a median household income of $99,805 describe the county. The county's voting pattern over the last decade is most similar to that of Grand County and Gallatin County.
