Remove the mandate and Obamacare withers and dies on its own.
Laws don’t just “die” without legislative action to make it happen. Otherwise, they lay dormant until someone else on another segment of the political spectrum wants to invoke the law.
Sure, Obamacare might prove unfundable. But it remains just as dangerous if it is not properly done away with.
For all intents and purposes it is already gone, it is not being enforced.
Remove the subsidies and the Medicaid expansion and it withers and dies even quicker.
