Over the course of five years, insurance coverage in Massachusetts has increased, premiums have decreased and virtually everyone has abided by the new requirement. While public opinion is favorable - two-thirds of Massachusetts residents support the law - the state does face challenges ensuring that the law is affordable. A report this year from the Massachusetts Taxpayers Foundation found that, in 2011, the law was responsible for an increase of just over 1 percent in state spending. The Massachusetts Legislature is now weighing legislation that would reduce the growth of health care costs.
