Nestled in Indiana's northeastern lake district, Steuben has delivered Republican presidential margins above 40 points in recent cycles, reflecting a rural, predominantly white electorate with deep conservative roots and little urban counterweight.
The Republican margin in Steuben County reached its widest at forty-eight points in 1920. The margin in 2024 was forty-two points, in line with the county's deep historical pattern.
Steuben County's loyalty is rooted in its place. Median household income of $74,911, a 93% non-Hispanic-white share, and a population of 34,726 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 DeKalb County and Warren County.
