I would say that Republicans who supported an individual mandate on people to purchase health care on the federal level and then strangely switched sides once the Democrats took up the cause (such as Mitt Romney and Newt Gingrich) come across as hypocritical or at least as people who didn’t have the same principles then that they now espouse. I personally disagree with a state or the federal government making the purchase of health insurance a requirement to be a requirement of just living in a state, because I see that as a major infringement on freedom. It is different from a state mandating auto insurance for drivers, because everyone is not required to buy it, just those who want to drive. And driving on the public roads is a privilege, not a right. As I wrote before, I believe states do have the theoretical legal authority to impose a requirement on their inhabitants to buy insurance, which the federal government does not have. If someone does not like it, like say, a citizen of Massachusetts, they could always move to another state. If the national government succeeds in imposing such a requirement, however, you have nowhere to go, except to leave the country altogether.
