On his first day in office, Mitt Romney will issue an executive order that paves the way for the federal government to issue Obamacare waivers to all fifty states. He will then work with Congress to repeal the full legislation as quickly as possible. In place of Obamacare, Mitt will pursue policies that give each state the power to craft a health care reform plan that is best for its own citizens. The federal government’s role will be to help markets work by creating a level playing field for competition.
