Jeffrey Toobin kind of goes H.A.M on the Roberts Court's use of "narrow" decisions to set the stage for right-wing revolutions:
The template here is the court’s voting-rights jurisprudence. In the 2009 case of Northwest Austin Municipal Utility District Number One v. Holder, the court upheld a challenge to an application of Section 5 of the Voting Rights Act. Chief Justice Roberts’s decision was “narrow,” and it even drew the votes of the court’s more liberal members. Four years later, though, Roberts used the Northwest Austin precedent as a wedge to destroy both Section 4 and Section 5 of the Voting Rights Act, as well as much of its effectiveness, in the case of Shelby County, Alabama v. Holder. The liberals who signed on to the Northwest Austin decision howled that they’d been betrayed. But it was too late.
