NASHVILLE--Make no mistake: Mitt Romney is proud of his sweeping health reforms in Massachusetts during his tenure as governor. But he's not proud to be an example of how it will work for the entire nation.

"I'm proud of what we did, and believe by virtue of what we did we helped save lives," the 2012 Republican presidential candidate told thousands during Thursday's keynote session at the America's Health Insurance Plans Institute 2015. "But it's right for Massachusetts; it's not right for what should be adopted for the entire country."

Romney's roughly 20-minute speech only briefly addressed health care -- instead focusing on poverty, federal debt, stagnant wages and other issues he says are hindering the country's success -- but he addressed the question of Romneycare in a short Q&A with Susan Dentzer, senior policy adviser of the Robert Wood Johnson Foundation and on-air health policy analyst.
