I don't meant to nitpick, but there is an important point to be made about Romneycare vs. Obamacare.
Romney's health plan was for Massachusetts. And as much as I like to think of myself as a fiscal conservative, as a resident of Massachusetts I have to reluctantly admit that the plan kind of works. For Massachusetts.
Obama's plan is national. It includes an individual mandate that all Americans purchase health insurance. That's a mandate from the Federal Government compelling people to go out and buy something. At the state and local level many of us tolerate and support this. At the Federal level this is unprecedented, and scary.
What works for Massachusetts may not work for the entire nation. As a state, we can do things like anti-smoking legislation and taxing junk foods to mitigate some of our health care risks. I don't think we can do that at a national level.
