Mower County anchors its economy around the Hormel Foods complex in Austin, giving it an unusually high share of Latino and immigrant workers for rural Minnesota. Despite that union heritage, the county has shifted more than 20 points toward Republicans over the past decade.
The Democratic margin in Mower County has rarely exceeded thirty-five points in modern history; the Republican margin has rarely exceeded sixty-eight points. 2024 delivered the county to the Republican candidate by ten points.
Mower County's demographics resemble the country more than they resemble most counties. A 75% non-Hispanic-white share, a 10% poverty rate, and a median household income of $73,074 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Des Moines County and Trumbull County.
