Thanks, Green Line!
I've merged my city-by-ward and suburb-by-township maps for a full map of Cook County.
Such a beautifully Democratic county. Outliers are Barrington in the NW - a rural wealthy suburb. Lemont and Orland in the SW - rural and white working class.
Other than that a whole lot of Democratic red. Biggest change since the 80s is in the northern portions. Skokie, Evanston, New Trier, Northfield, Wheeling, Schaumburg, etc would have been mostly to solid GOP 30 years ago - now solid Dem.
I think Wheeling, Schaumburg, and the surrounding suburbs still lean slightly R; the reason they're solid D here is mostly favorite son effect.
BTW, where do you get your templates? I'd like to try to work on a statewide map for Illinois.
