It's true that Obamacare has not been popular, but the concept of a federal health insurance program of some type is. The cost of healthcare, the denials of some people from healthcare insurance and the quality of what we get for our money is pretty bad. This is an issue that is non partisan. There are plenty of conservatives that can see that the medical establishment is not serving us well.
There's already a federal insurance program called Medicare. That could have been expanded relatively easily. Also, Trump is 100% correct that removal oft he interstate barrier would open the market to more competitive pricing.
This boot on your neck mandate, I mean "tax", is unconstitutional on the face of it- regardless of Chief Patsy Roberts "opinion". There! I said it!
