Well I spent about 18 hours in Chi-town yesterday. And Springfield is still there. So... Unless everything burned to the ground some time today I would bet on "never".
The Land of Lincoln is probably top 10 for most corrupt places on planet earth. Four Governors imprisoned in 35 years. Videoing/recording police is a Felony with a capitol "F". Road Blocks, profiling, warrantless searches, Police torture squads. Toll Road "Authority". Secretary of State Police. No death penalty because roughly 75% of the convictions were overturned. The state has agriculture, manufacturing, entertainment, gambling, R&D, hunting, fishing, O'Hare airport, railroads, Canals, lake Michigan... and the entire state is bankrupt.
