In the Philadelphia Inquirer, my hometown paper, I critique the Supreme Court’s decisions on gay marriage and Obamacare. As a policy matter, I supported gay marriage, but the Constitution reserves the question for the voters of each state, not the judicial process. The weakness of the Court’s reasoning — is it Due Process? Is it Equal Protection? — suggests the decision’s political nature. Many may celebrate the result, but they should not welcome the steady erosion of democratic self-government.

Indeed, the political nature of Obergefell becomes readily apparent in the contradictory, vague logic of the majority opinion by Justice Anthony Kennedy. The holding fits within none of the established precedents governing the due-process and equal-protection clauses. Kennedy says marriage is a fundamental right, but he admits that American society had long understood that right to be only between a man and a woman. He suggests that the right to equality may require gay marriage, but gays do not receive the heightened constitutional protection reserved for racial and religious minorities. Kennedy could have recognized that gays should receive the same protections against discrimination as gender, but he could not because recognizing sexual orientation as a protected class might open up a Pandora’s box of new constitutional claims by every self-defined group.
