Livingston County sits on Detroit's outer suburban ring, where low-density growth and a predominantly white, college-educated-but-conservative electorate have produced some of the widest Republican presidential margins in the state for two decades.
The Republican margin in Livingston County reached its widest at fifty-two points in 1952. The margin in 2024 was twenty-four points, in line with the county's deep historical pattern.
Livingston County's loyalty is rooted in its place. Median household income of $103,039, a 94% non-Hispanic-white share, and a population of 195,833 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 Indian River County and Greene County.
