If any one state stands out in the race to the bottom of public employee pension insolvency, Illinois would be it. And GOP Governor Bruce Rauner is steeling himself to prevent a collapse. Rauner, a former private equity fund manager, was elected last November over Democratic incumbent Pat Quinn. He faces $111 billion in unfunded pension liabilities, or about $8,500 per resident. The years of greed, corruption and bad luck having taken a toll, the governor and his top fiscal policy adviser, Donna Arduin, have proposed tough measures to reverse course. So far, they haven’t won any friends among public-sector unions - or the Illinois Supreme Court, which on May 8 sided with the unions in invalidating reforms enacted in late 2013.
