Yeah. The government is really eager to relinquish control once they've nationalized something. Take ACA - the Republicans couldn't bring themselves to repeal it even though they were elected on that promise. Do you really see Congress letting go once they have total control of our health care?
Were they elected on that promise? They only reason they "won" was because of the EC and Gerrymandering.
The real reason they didn't repeal it is because too many of their own inbred, bible thumping voters will figure out that the ACA that gives them health care is the same thing as that ObamaCare they hate so much.
