Grant County, a rural enclave north of Lexington, recorded an R+64.8 presidential margin in 2024, placing it among the state's most one-sided results. Its small population and agricultural economy mirror broader trends in Kentucky's exurban counties.
The Republican margin in Grant County reached its widest at sixty-five points in 2024. The margin in 2024 was sixty-five points, in line with the county's deep historical pattern.
Grant County's loyalty is rooted in its place. Median household income of $69,178, a 93% non-Hispanic-white share, and a population of 25,418 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 Pendleton County and Harrison County.
