The Supreme Court vacancy created by Ruth Bader Ginsburg’s death leaves the Affordable Care Act in much greater jeopardy than it was just a few days ago.

The big picture: Conventional wisdom had held that Chief Justice John Roberts would likely join with the court’s liberals to save the ACA once again. But if President Trump is able to fill Ginsburg’s former seat, Roberts’ vote alone wouldn’t be enough to do the trick, and the law — or big sections of it — is more likely to be struck down.
