The only way they could get away with not repealing ObamaCare would be if they were to get rid of the mandates and make the costs be privatized or voluntarily assumable by State governments or NGO’s who want to save it.
For example, George Soros could breath a few weeks life into ObamaCare by paying for all the high risk pools himself. It won’t leave him any money left for politics but he would at least get to leave behind of legacy of being known as one who cared instead of being a powermonger. Same goes for the ACLU and other organizations.
Getting rid of the mandates & hardships that the law imposes is all that we really need. After doing that the ObamaCare will implode all on its own as the carriers exit the markets for 2018 and for sure by 2019. And what would replace it: the free market.
Now yes there are some charity matters to consider regarding the high risk pools of people. On that the following approach is needed:
1. Start enforcing the laws against health care providers that violate racketeering, monopoly, price-fixing, and other fraudulent activities.
2. Come up with a solution that mixes charity & responsibility.
