Health-care reform, the impossible dream that seemed to become a reality in 2010, is now in mortal danger. Republicans want to repeal it even though the federal law is patterned after a Massachusetts law that their apparent presidential nominee signed in 2006. They can't do that, of course, unless they sweep the next election. So the clear and present danger comes from the Supreme Court, where a majority of justices seemed to snarl at the law in open session last month. Health-care reform is clearly in legal peril.
