WHICH IS WHY IT WAS A CONSERVATIVE PROPOSAL IN THE FIRST PLACE:

During a more than 10-minute back-and-forth on health care largely between Romney and former Pennsylvania Sen. Rick Santorum, Romney ended up delivering a lengthy justification for his state's decision to pass a 2006 law that included requiring nearly every resident to either have health insurance or pay a tax penalty.

"If you don't want to buy insurance, then you have to help pay for the cost of the state picking up your bill, because under federal law if someone doesn't have insurance, then we have to care for them in the hospitals, give them free care," said Romney. "So we said, no more, no more free riders. We are insisting on personal responsibility. Either get the insurance or help pay for your care."

"Does everybody in Massachusetts have a requirement to buy health care?" asked Santorum?

"Everyone has a requirement to either buy it or pay the state for the cost of providing them free care," Romney shot back. "Because the idea of people getting something for free when they could afford to care for themselves is something that we decided in our state was not a good idea." [...]

Said John McDonough, a professor at the Harvard School of Public Health, "Romney has given in this entire presidential campaign last evening what I believe is the most effective and persuasive rationale and defense of the individual mandate."
