Long before the scandal-plagued candidate Scott Lee Cohen emerged victorious in last week’s primary election, many were asking whether we even needed a lieutenant governor. What does the post entail, besides a wait for the governor to resign, be impeached or die? Still, now that Cohen has stepped down, 38 people led by House leader Michael Madigan will now search for another Democrat to fill the post. That process dismays incumbent governor and current Democratic gubernatorial nominee Pat Quinn. Quinn hinted he might ask legislators to change how we elect the Lieutenant Governor. To learn more about the process and why we do it differently than other states, we turn to an expert in the field of state politics, Kent Redfield a professor emeritus of political science at the University of Illinois at Springfield.
