Illinois holds one of the sharpest urban–rural divides in the country, and a single county draws the line. Donald Trump carried 88 of the state’s 102 counties outright in 2024 and lost Illinois by 10.9 points — because Cook County, which holds Chicago and casts 37 percent of the statewide vote, went Democratic by 41.6. Cook’s net Democratic margin, about 864,000 votes, is larger than the statewide margin itself: across the other 101 counties combined, Trump finished about 250,000 votes ahead. The state is Democratic on the strength of Chicago, and Republican nearly everywhere else.

The map sorts by distance from the lake. The five collar counties around Cook gave the Democratic candidate four of their five margins — Lake by 20.7 points, DuPage by 13.1, Kane by 9.3, Will by 1.6 — with McHenry the lone holdout at 5.3 Republican. Downstate runs the other way and runs deep: Edwards County, in the far southeast, voted Republican by 71.1 points, with Wayne County beside it at 70.9. The Democratic islands beyond Chicagoland are the university and river towns — Champaign, home to the University of Illinois, at 23.8 points, and St. Clair County, which holds East St. Louis, at 7.8.

Illinois moved with the country in 2024, its Democratic margin slipping from 16.9 points in 2020 to 10.9, and about 418,000 fewer ballots were cast than four years earlier. The state underneath is the nation’s sixth-largest, at 12.7 million, and built on migration: 18.8 percent Hispanic or Latino, most of Mexican origin, and 13.3 percent Black, with German, Irish, and Polish the deepest European lines. It ranks 10th in Catholic adherence and 12th in college degrees. In 2026 Governor JB Pritzker seeks a third term against Darren Bailey, and the U.S. Senate seat is open — Dick Durbin retiring, with Juliana Stratton and Don Tracy contesting it.
