the law was written with the intent that the very generous subsidy's would be used in state based exchanges, not the federal ones. so states that say no are basically shielding their citizens of obamacare and all the mandates, taxes and job killing this law does. oklahoma is suing the feds bc the irs came out with a ruling saying"no, subsidy's can be used in both", but thats not the case.so if we have a fed based exchange, it will be hollow. then, in an ironic twist, states that say no, will attract jobs and businesses from states that do set up an exchange and have obamacare hanging over their heads. how bout that? a state will attract jobs if it says no to the exchange.
