Home to Decatur, Macon County backed Democratic presidential candidates as recently as 2008 but has since swung nearly 30 points, reflecting broader trends among Midwest counties with mid-size manufacturing economies and declining union density.

The Republican margin in Macon County reached its widest at forty-two points in 1928. The margin in 2024 was nineteen points, in line with the county's deep historical pattern.

Macon County's loyalty is rooted in its place. Median household income of $62,666, a 74% non-Hispanic-white share, and a population of 101,849 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 Henderson County and Pulaski County.
