Kankakee County, anchored by its small industrial city on the river of the same name, has drifted steadily rightward over two decades — its 2024 presidential margin of R+20.8 reflects a broader rural and exurban realignment across downstate Illinois.

The county's recent history is a story of close margins. The Democratic margin reached thirteen points in 1964; the Republican margin reached sixty-two points in 1920. Most other elections have been decided by single-digit points.

Kankakee County's demographics — a population of 106,635, a 73% non-Hispanic-white share, a median household income of $71,281 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Lenawee County and McDonough County.
