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.

Union County's R+40 presidential margin in 2024 reflects a broader eastern Oregon pattern where ranching and timber economies correlate with some of the state's widest partisan gaps, even as the county seat of La Grande anchors a small university-town counterweight.
Across the recorded series it reached a Democratic high of 46.6 points in 1936 and a Republican high of 40.4 points in 2020. The 2024 margin was 40.0 points.
A population of 26,144, a 86% non-Hispanic-white share, and a median household income of $65,661 describe the county. The county's voting pattern over the last decade is most similar to that of Rio Blanco County and Sheridan County.
