For all the drama surrounding the Commerce Clause challenge to the individual mandate provision of the Patient Protection and Affordable Care Act ("PPACA"), the doctrinal question presented is simple. Under existing doctrine, the provision is as valid as can be. To be sure, the Supreme Court could alter existing doctrine, and many interesting things could be written about the dynamics that sometimes prompt judges to strike out in new directions under the pressures of cases like this one. But it is not my intention to pursue that possibility here. My own suspicion, for what it is worth, is that the Supreme Court will abide by its previously announced doctrines and uphold the individual mandate. So I mean to engage U.S. Department of Health and Human Services v. Florida as the easy case it is and to explore an underappreciated feature of how it came to be so easy.
