Well said Darla. The individual mandate is a pro-business concept and Repubs only opposed it when Obama adopted it as a compromise versus having a public option.
Politically speacking the far reaching consequences of the this decision are profound. There's no going back now. If nothing else inertia will keep HC reform rolling. However, the aspects of ACA which have been implementd are already quite popular (ending pre-existing condition exclusion and allowing parents to keep adult children on their insurance till 25), as other aspects of ACA are implemented they will become very popular too. The question being, what will be the backlash on Repubs for their stiff oppostion? Will there be a significant price to be paid by Republicans down the lane?
