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.

Blaine County's Fort Belknap Indian Reservation shapes its electorate in ways that set it apart from surrounding Hi-Line counties, and the 2024 presidential margin of R+5.9 reflects a competitive mix absent in most of rural Montana.
Across the recorded series it reached a Democratic high of 42.8 points in 1936 and a Republican high of 31.7 points in 1920. Between 2020 and 2024 the county moved 9.7 points toward the Republican candidate; the 2024 margin was 5.9 points.
A population of 6,949, a 44% non-Hispanic-white share, and a median household income of $64,813 describe the county. The county's voting pattern over the last decade is most similar to that of Big Horn County and Roosevelt County.
