What’s More Revolutionary Than Overturning Obamacare?

Simon Lazarus and Dahlia Lithwick parse one of the most obscure, but possibly consequential, parts of the pending health care litigation:

[T]he real surprise [was that] the court also agreed to hear a fourth issue, also for an hour: the claim of the 26 Republican state officials that the ACA’s expansion of Medicaid coverage should be struck down, on the ground that it unconstitutionally “coerces” state governments. Potentially, the court’s disposition of this issue could cripple the federal government’s capacity to promote national policy goals more gravely than even a decision to overturn the ACA individual mandate, and thereby limit congressional authority to regulate interstate commerce.
