Jackson County's agricultural southwestern Minnesota landscape correlates with a 42-point Republican presidential margin in 2024, among the widest gaps recorded in a state that remains closely contested at the statewide level.
The Republican margin in Jackson County reached its widest at seventy points in 1920. The margin in 2024 was forty-two points, in line with the county's deep historical pattern.
