It is not entirely clear to me what happens
If a state chooses not to participate and grow Medicaid.
It may be that the uninsured poor end those states end up being on the hook a considerable portion of what they “make” now in refundable tax credits in order to “pay” for their new “insurance” policies.
Medicaid will have to be rationed, or the people of the state will have to accept a massive tax increase to pay for it. The feds will only pay for it until everything is in force (I think the bill allowed 2 years?). That's when the states taxpayers get the shaft. They won't know about this "new crises" until after the election if no one tells them ( and you know the democrats will never waste a good manufactured crises. They didn't set the bill up this way for nothing. They'll save us all by coming in with a "new way" (single payer), because the "old way" (private insurance) didn't work.)
Americas health care system was working just fine until the left decided to break it and take it.
