At a 2008 event in New Hampshire, Romney was asked by a voter, "You supported national healthcare in Massachusetts. Are you going to do the same thing on a national?" His response: "Absolutely, I've already put a plan out. Take a look at it. Get on my website, take a look."
Later the same voter followed up with Romney.
Romney's 2008 health care reform plan implies using a “federalist approach,” but the plan doesn't specifically imply that it is a states-only approach. Implementing the concepts laid out in the Romney plan, including the “Stop The Free Riders” concept, also known as the individual mandate, would most likely have to involve some coordination on the federal level.
