Rapid suburban growth southwest of Chicago has transformed Kendall from a lopsided Republican stronghold into a genuine tossup, with the 2024 presidential margin settling at just 1.5 points Democratic.
The county's recent history is a story of close margins. The Democratic margin reached seven points in 2008; the Republican margin reached seventy-seven points in 1920. Most other elections have been decided by single-digit points.
Kendall County's demographics — a population of 137,675, a 65% non-Hispanic-white share, a median household income of $111,601 — 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 Virginia Beach city and Duval County.
