Livingston County's R+46.3 margin in 2024 places it among the state's most lopsided presidential results, reflecting a predominantly rural, small-town electorate where agriculture and manufacturing have long anchored both the economy and voting patterns.
The Republican margin in Livingston County reached its widest at fifty-two points in 1920. The margin in 2024 was forty-six points, in line with the county's deep historical pattern.
Livingston County's loyalty is rooted in its place. Median household income of $73,790, a 89% non-Hispanic-white share, and a population of 35,565 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 Gasconade County and Cameron County.
