Rod Blagojevich: Following an Illinois Governor Tradition

But this is political story that goes beyond just Blagojevich. Along with the position of Newark, New Jersey mayor the seat of Illinois Governor may be the most corrupt office in America. Not all governorships are created equal. Some governors have virtually no power (Vermont) and some have a lot (Massachusetts and Alaska). On the sliding scale, Illinois Governors do have a lot of power. They also have a wrap sheet. If Blagojevich is convicted he will become the fourth Illinois Governor in 40 years to go to jail. Other than Ryan, former governor Dan Walker took fraudulent loans to repair his yacht. Gov. Otto Kerner (as in Kerner Commission) was convicted of taking bribes while in office.

What the hell is it about being Illinois governor that makes whoever holds that office get into trouble? Is it something they put in the water that runs through the governor's mansion in Springfield?
