WHEN a majority of Supreme Court justices adopt a manifestly ideological agenda, it plunges the court into the vortex of American politics. If the Roberts court has entered voluntarily what Justice Felix Frankfurter once called the “political thicket,” it may require a political solution to set it straight. The framers of the Constitution did not envisage the Supreme Court as arbiter of all national issues. As Chief Justice John Marshall made clear in Marbury v. Madison, the court’s authority extends only to legal issues.
