Hardin County's presidential margins have widened steadily over the past three cycles, reaching R+38 in 2024 — a shift driven by a largely rural, agriculture-dependent population with one of the state's lower population densities.
The Republican margin in Hardin County reached its widest at seventy points in 1920. The margin in 2024 was thirty-eight points, in line with the county's deep historical pattern.
Hardin County's loyalty is rooted in its place. Median household income of $65,069, a 91% non-Hispanic-white share, and a population of 16,639 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 Wright County and Hamilton County.
