Obamacare’s days may be numbered. The Affordable Care Act has survived dozens of recall attempts by the House of Representatives and two challenges brought to the U.S. Supreme Court.  But with a Donald Trump presidency and a new Republican-led House and Senate, the bill—or at least certain key provisions—is almost certainly headed for the chopping block.

The question now is what provisions may survive and when the death knell of the others will sound.

President-elect Trump campaigned on repealing the law and its requirement for Americans to carry health insurance. Trump says the private market should step in with the sale of insurance plans across state lines to help drive down costs through competition. He has said he will dismantle Medicaid and transform it into a system of state grants to provide assistance for low-income residents.
