ANOTHER ONE BITES THE DUST:   Massachusetts is scrapping its Obamacare exchange, following on the heels of Oregon.  I wonder if these decisions have anything to do with the Halbig v. Sebelius case pending in the D.C. Circuit?  If the court in Halbig rules for the plaintiff, neither tax subsidies nor the employer mandate would apply in those States that opt-out of running their own exchanges.  Governors in red states would likely applaud this result, but Governors in blue states like Oregon and Massachusetts would not.  It’s just a thought.
