Justices on the U.S. Supreme Court this morning considered what to do with the rest of President Obama’s national health care law if its individual health insurance mandate is struck down. Though it was difficult to get a clear read on their thinking as they asked tough questions of all sides, the Court seemed open to the possibility of overturning the entire law.

Paul Clement, arguing for the 26 states challenging the law along with the National Federation of Independent Business, started off the arguments by suggesting the Court look at whether Congress would have passed the law without the individual mandate.
