Roberts’s intellectual complexity does not prevent him from expressing himself pithily, as he did with those words when dissenting in a case from Arizona. Joined by Antonin Scalia, Clarence Thomas and Samuel A. Alito Jr., Roberts’s dissent should somewhat mollify conservatives who are dismayed about his interpretive ingenuity four days earlier in writing the opinion that saved the Affordable Care Act. Furthermore, they, including this columnist, may have missed a wrinkle in Roberts’s ACA opinion that will serve conservatives’ long-term interests.
