BOSTON -- Three years after the inception of Massachusetts’ landmark health reform legislation, which required every citizen to buy insurance, NewsCenter 5’s Ed Harding wondered what former Gov. Mitt Romney, a key political architect of the plan, thought of its progress.

Call it protecting his legacy, well-earned pride, or seeing the glass as half-full, but Romney says Massachusetts deserves an ‘A.’

“It’s working like we had hoped it would work,” the one-time republic presidential candidate said. “We got nearly everybody in Massachusetts health insurance, which really, something people didn't think was possible.”

Romney said the same can be done nationwide, though he concedes what many in the Bay State are grappling with now, that the hardest part of the reform debate is controlling costs. It is projected that within a decade health care will account for 20 percent of all money spent in the United States.

Currently, health care accounts for between 17 and 18 percent of the United States’ gross domestic product.

“It’s huge,” said Romney. “We’ve got two challenges. One is to get everybody insured. Believe it or not that's the relatively easy job. The other job is to reign in the inflation associated with health care. We can do that too but it's a lot of work.”

Romney points to a recent analysis by the pro-reform Massachusetts Taxpayers’ Association, showing that since near-universal coverage was implemented in 2006, state taxpayers have had to shell out an additional $88 million per year to insure an additional 430,000 citizens.

“Some people say. ‘Oh, it's expensive,’ but actually, it cost less than two percent of the state budget.”

Romney is closely following the reform debate in Washington, DC, and pointed to President Barack Obama’s proposal for a government-run so-called public plan option as a “big mistake.”

“The current system with over 1,000 insurers in this country, is perfectly capable adequate to provide choice to people in America,” Romney said.

The former governor declined to answer when Harding asked if health care is a right of a privilege in the United States. He did insist, however, that on a national level politicians ought to be able to create a system where every citizen has health insurance.
