Le Sueur sits in south-central Minnesota's agricultural belt, where a decades-long shift away from competitive presidential results has left the 2024 margin at R+33.6 — roughly double what it was a decade prior.
The Republican margin in Le Sueur County reached its widest at thirty-six points in 1920. The margin in 2024 was thirty-four points, in line with the county's deep historical pattern.
Le Sueur County's loyalty is rooted in its place. Median household income of $94,968, a 91% non-Hispanic-white share, and a population of 29,113 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 Wabasha County.
