One year ago today, we were not talking about same sex marriage or voting rights. The topic du jour was the U.S. Supreme Court's (SCOTUS) dramatic and surprising ruling on the constitutionality of the Affordable Care Act/Obamacare.

Were it not for a late change of mind/heart by Chief Justice John Roberts, the entire law would have been overturned. Instead of throwing out the ACA or the individual mandate, the only significant change was the "Roberts' Rule" that made the ACA's mandatory Medicaid expansion an option for states.
