Obamacare appears to be headed back to the U.S. Supreme Court. On Tuesday the U.S. Court of Appeals for the D.C. Circuit and the U.S. Court of Appeals for the 4th Circuit issued dueling opinions on the legality of an I.R.S. rule which provides tax credits to individuals who purchased their health insurance from federally run health care exchanges. That circuit split makes it likely the Supreme Court will get involved.
