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.
Across the recorded series it reached a Democratic high of 17.5 points in 1964 and a Republican high of 70.4 points in 1920. Between 2020 and 2024 the county moved 6.3 points toward the Republican candidate; the 2024 margin was 38.3 points.
A population of 16,639, a 90% non-Hispanic-white share, and a median household income of $65,069 describe the county. The county's voting pattern over the last decade is most similar to that of Wright County and Hamilton County.
