seems like Obamacare might really be dead

so here is how I understand it. Eighteen states brought suit claiming that since there is no mandate, the whole ACA law is unconstitutional. This suit has worked its way up the ladder with the last court deciding in favor of the states. It has now been pushed to the Supreme Court for a final decision. If the vote is 4-4, then the lower riling will stand and we kiss ACA goodbye. A 4-4 vote would assume Roberts votes with the 3 remaining Democrats.
