Four Words and Seven Million Americans

The Supreme Court found Obamacare to be constitutional two years ago.  Today it was asked to decide a legal challenge. Does the law provide that subsidies for low-income people apply only where health insurance markets have been "established by the state?" The Court's interpretation of those four words could determine if subsidies are valid for seven million people who signed up where the federal government established the markets. It's a case deeply rooted in partisan politics. Four liberal court members and two conservatives made clear what they think.  Chief Justice John Roberts could be the decider — but he was hardly heard from.
