Thanks for the explanations. It will be interesting to see whether the courts do as MT predicts, and rule in favor of Obama, or as Sarnoff predicts, and uphold this current ruling, which I take it might completely unravel Obamacare.
Even if the current DC Circuit ruling is upheld all the way through the USSC, it probably wont do anything at all to Obamacare in the long run. If it isnt addressed legislatively over the years between now and a possible USSC decision, it will have an impact on people who got subsidies through federal exchanges but it wont strike down ACA or impact the millions of people who got subsidies through State exchanges. But just like Medicaid, eventually every state will participate in Obamacare and have an exchange. There is just too much money at stake for them not too. Over the long run, politicians who oppose setting up the State exchanges will be voted out by taxpayers who want expanded healthcare benefits and options and the subsidies. What you are seeing now is short term political stuff going on which has to do with the short term political goals of the parties and players involved. Long term, every state will have an exchange.
But like I said above, I doubt it even goes to the USSC.
