I expect the first priority for the Republicans now will be reversing everything done under Obama. Even the thing they agree with, they can't allow a Democrat to claim the success. I expect a health care reform repeal act to pass at some point in 2017.
I actually suspect they will simply adopt it back as their own. It would be a vote destroyer to erase it. If they simply triangulate it back to the original RomneyCare implementation and say it was their idea all along -- rewrite a bit of history -- it'll go well with their base. Costs them nothing, really. And it's not like they haven't done it before.
Remember, both Rs and Ds are beneficiaries of the ACA.
