Scott County sits in the fast-growing Twin Cities exurban ring, where rapid population growth and an influx of younger, college-educated residents have steadily compressed margins that once ran well into double digits for Republicans.
The Republican margin in Scott County reached its widest at forty-two points in 1892. The margin in 2024 was eight points, in line with the county's deep historical pattern.
Scott County's loyalty is rooted in its place. Median household income of $119,314, a 77% non-Hispanic-white share, and a population of 154,557 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Floyd County and Mineral County.
