“I reject the idea that Illinois politics should be defined by its worst actors,” Gov. J.B. Pritzker told the Democratic faithful in Cook County last week.

That’s a wishful sentiment that rings hollow in the face of the federal investigation engulfing the Capitol. How many Illinois lawmakers are on the U.S. attorney’s latest list of “worst actors”? What exactly was going on between the General Assembly and the state’s largest electric utility?

Ethical righteousness is a cyclical thing in Springfield, invariably triggered by a spectacle of staggering public corruption exposed by the feds. The 2003 State Officials and Employees Ethics Act was prompted by the licenses-for-bribes scandal that sent Gov. George Ryan to prison. Another bout of reform fever followed the impeachment and conviction of Gov. Rod Blagojevich, now imprisoned for trying to shake down the CEO of a children’s hospital for campaign cash, among other things.
