Licking County sits just east of Franklin County and has absorbed significant population spillover from Columbus, yet its presidential margins have widened toward Republicans even as its suburbs densify — a pattern that cuts against typical exurban realignment trends.
The Republican margin in Licking County reached its widest at forty-five points in 1984. The margin in 2024 was thirty points, in line with the county's deep historical pattern.
Licking County's loyalty is rooted in its place. Median household income of $84,426, a 86% non-Hispanic-white share, and a population of 181,837 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 Madison County and Steuben County.
