Interesting additional detail on how the states are reacting to the case:
http://www.businessweek.com/news/2014-11-11/state-obamacare-strategies-take-shape-as-court-case-loomsSo in the end if SCOTUS rules against the Obama admin it is likely that a majority of states will still end up getting the subsidies via workarounds. But there will be a handful of states that take the 'screw you' position and refuse the money and free subsidized healthcare for their citizens. West Virginia is a surprise because they have Dem gov who did expand Medicaid via Obamacare. Unclear how you can be for Medicaid expansion (which actually costs the state something) and not the subsidies (which will cost nothing).
