Going back to 1960, the following governors have been indicted, Kerner, Ogilvie, Walker, and Ryan. Since 1960 only TWO governors have not been indicted. That is a record which is without precedent. This present governor looks to be headed to join company with the preceding majority.
I don't believe Ogilvie was ever indicted.
It is even worse since of the two who weren't convicted one served forever and a day, Big Jim Thompson the Republican who got there by sending crooks to jail.
