Problem
In National Federation of Independent Business v. Sebelius, the Supreme Court examined the constitutionality of two parts of the Affordable Care Act: the individual mandate and the Medicaid expansion. What two theories did the government argue to support Congress' imposition of the individual mandate? What is the individual mandate and what did the Court find with respect to each theory? What is the Medicaid expansion and what did the Court find with respect to its constitutionality?
