Cornerstone of Obama Presidency Collapsing / The Politics of Saving 'Granny'

How did Obama ever think that his program would pass constitutional muster? How could he imagine that the Interstate Commerce clause could cover something that wasn't interstate (health insurance cannot be sold over state lines) and wasn't commerce (failure to buy insurance is not commerce) would stand up in court? He was so sure that he would win any constitutional challenge that he arrogantly failed to put a severability clause in the bill so that it would survive even if parts were stricken down.
