The ruling would impact the subsidies which, as the referenced article states, would effectively financially destroy the law. The law itself would remain, but the subsidies would be struck down. In that case, McTurtle and the rest of the traitors would absolutely be able to add a few words and fix the issue, I would assume. However, the fact is that getting rid of the subsidies in states that DIDN'T create exchanges would cause millions to lose their coverage overnight, essentially. Enter single payer.
