Illinois' largest union is backing Governor Quinn over Bruce Rauner. AFSCME made the announcement over the weekend. The union has had a tumultuous relationship with Quinn since he's been in office. They went to bat with Quinn after he refused to honor pay raises for thousands of workers. He claimed lawmakers did not put the cash in the budget but a judge eventually told him to pay up with interest. Unions also disagreed with Quinn on the pension issue. Despite the disagreements, union leaders say Quinn is the better candidate than Rauner.
