Historical Corruption & Blagojevich
It turns out, however, that Illinois isn't even in the top five of most corrupt states--at least according to statistics from 1997 through 2006 compiled by Corporate Crime Reporter. Of the nation's 35 most populous states, which is the most corrupt? Louisiana. Illinois ranks 6th.
