No single payer, no public option, not even a weak public option. Sure, the ACA was a big bill, but he didn't really go that big.
Obama did what he could under the restrictions of the political era. The rules of politics in the United States have to be rewritten to allow that stuff to go through. The ACA was barely acceptable.
But time will produce the demand for comprehensive health insurance particularly as Trump's policies fails to help the working class that voted for him. The intensified need for healthcare reform to help those left behind by globalism will produce the majority Democrats need.
I pretty much agree with everything TD is saying. From LBJ creating Medicare/Medicaid, the Dems have always made UHC an ultimate goal... Not necessarily a system like the NHS in the UK, but closer to what Canada and Germany have. If the Dems win control of the government in 2020 or 2024, they will add in a public option, expand medicaid, lower the participation age for Medicare to 60, and add in drug/test negotiation to bring down costs. They can use the tax system to ensure that everyone can afford a plan... by making small additions/adjustments to the ACA, the Dems can create functional UHC... the framework is there, and now we know it's durable.
The idea of a free-market health care system in the US, Paul Ryan's dream, is dead.
