With the future of the Affordable Care Act in doubt after last week’s hearing before the U.S. Supreme Court, Republican lawmakers are busily preparing back-up legislation. New options should not be necessary—the government should prevail against those challenging its interpretation of the Act’s premium subsidy provisions. But it is prudent to consider alternatives in the event that the Court rules against the government.

While most of the ideas being floated would do little to bring health care insurance to the uninsured, there is an option that really could expand access to coverage while also containing health care spending. And it could be attractive to Republicans and Democrats alike on Capitol Hill.
