The following is from an article by Andrew Romano writing at The Daily Beast.
Back in 2004, 2005, and 2006 a very intelligent, very meticulous man spent a lot of time studying health-care reform. Eventually, he concluded that universal private coverage would only be possible if people were required to pay a fee when they refused to buy insurance. “It’s a kind of mandate,” he explained. “Help everybody get in the pool. That brings down the cost, and at the same time [it] makes sure that people don’t have to worry about losing their coverage... We want everybody in the system. No more free riders.” His name was Mitt Romney. A year or two later, one of Romney’s fellow Republicans praised his Massachusetts reforms, saying “well, that’s something that I think we should do for the whole country.” His name was Jim DeMint.
