From the Boston Globe:
Asked today whether Romney was ill-advised in implementing Massachusetts’ system, Huntsman said he believed Romney did not understand that a mandate would lead to increased premium costs. “As we look back now, I think he would see it as an ill advised move,” Huntsman said.
The Huntsman campaign pointed to a study by the Beacon Hill Institute at Suffolk University, which documents both the higher costs to the state of Massachusetts from the health care reform, and the increased premiums for Massachusetts insurance plans after health care reform took effect. According to that study, the average cost of a family insurance plan increased by $2,500 between 2006 and 2009.
