Wisconsin is 100% the worst state geographically for democrats
Illinois is up there, but it's covered up by how well they do statewide. IL Dems are toast if they ever lose control of redistricting. MN used to be Dem-favorable geography but is rapidly deteriorating as they lose everything more than an hour away from MPLS.
Eh, Chicago 100% makes Illinois a blue state, but it also is the vast majority of the population. Out side Chicagoland is only 5-7 congressional seats of the 16 the state has. Dane and Milwaukee are each about 1 seat, but also some of the bluest regions in the country
