This article predates today's decision and is a critique of a lower court ruling in the same case. The language in the law is actually contradictory, very contradictory.
Frankly, if memory serves, the authors of the bill we're having the same political calculations that Icenine echos in post 11 above. They specifically identified the state exchanges as the vehicle for subsidy distribution to put political pressure on the states to set up their own exchanges. Remember that PPACA made available quite a bit of money to states to incent them to create their own exchanges as well. So much for the argument about "Congressional intent" in this case.
Of course maybe if Dems like Pelosi would have found out what was in the bill before they passed it, we wouldn't be having this issue right now.
