Swift County sits in west-central Minnesota's glaciated plains, where a shrinking and aging agricultural population has driven presidential margins from competitive to Republican-dominant over the past two decades.
The 2016 election was the turning point, when the Republican candidate carried the county by twenty-six points. The 2024 margin was thirty-four points, in line with the county's new direction.
The demographics suggest why. A population of 9,748, a 88% non-Hispanic-white share, and a median household income of $60,412 situate the county in the broader realignment patterns of recent cycles. The county's voting pattern over the last decade is most similar to that of Cowlitz County and Pepin County.
