Welfare: During the debates on ObamaCare, Medicaid got little attention. That was a mistake, since enrollment and the cost of treating all those jumping onto the program is surging beyond expectations.
At first, ObamaCare tried to force states to expand eligibility for Medicaid by including childless adults and people with incomes 38% above the poverty line. In 2012, the Supreme Court blocked this attempt, making expansion optional for states.
