Elections are about votes and there is one heck of free state army types in Chicago that vote. Add to that the Madison and St Clair county ones, the AFSCME, teachers unions and the r est on the Democrat payroll and you have a very formidable opponent come election day. Many just choose to leave the state knowing it cant be repaired without a full scale collapse and, if you think it can't collapse, just look at Granite compared to a few decades back. Check out Venice, Madison and Belleville, which I call East St. Louis II.
It will happen and the Democrats will move too taking their pensions with them.
