Kandiyohi County, anchored by Willmar and its meatpacking industry, has shifted steadily rightward over the past two decades, posting a 30.9-point Republican presidential margin in 2024 despite a notably diverse immigrant workforce in its largest city.
The Republican margin in Kandiyohi County reached its widest at seventy-three points in 1904. The margin in 2024 was thirty-one points, in line with the county's deep historical pattern.
Kandiyohi County's loyalty is rooted in its place. Median household income of $76,592, a 79% non-Hispanic-white share, and a population of 44,079 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 Mille Lacs County and Kanabec County.
