I know this isn't Illinois, but the basic dynamics are the same. Bobby Schilling has made these same wild claims himself. The gist of his claim is based on a Forbes/Manhattan study that compares the cost of the three cheapest pre-ACA insurance plans against the three cheapest plans today. The problem is that before the ACA there were few standards that insurance plans had to meet. Consumer Reports did a piece on these plans saying that they weren't really insurance at all due to their skimpy coverage. Insurance plans today MUST cover things like pre-existing conditions, maternity care, and can't kick you off when you get sick.
