Its not only Chicago but the entire state.
IL is controlled by 'the Combine'. They work with (bribe) anyone of either party. Sometimes you wonder if they don't actually pick both candidates ('semi' joking).
And how you missed the threads on our past criminal Gov, George Ryan (RINO-Convicted FELON), and his criminal conspiracy trial.. I don't know? And it was thanks to him and his criminal 'R' cronies that the IL GOP is in total shambles and literally gave all state offices to the RATS that the GOP had controlled for decades.
(If you have the time go to Drudge, find the Chi Tribune link then go there and find John Kass's articles on 'The Combine'.)
People usually get who the majority want. I've concluded that only crooks or soon to be crooks can get elected in Chicago.
