Is Polygamy Next?

NOW that the dust is settling from the Supreme Court’s decision in Obergefell v. Hodges, which recognized a right to same-sex marriage, there are new questions. In particular, could the decision presage a constitutional right to plural marriage? If there is no magic power in opposite sexes when it comes to marriage, is there any magic power in the number two?

Chief Justice John G. Roberts Jr.’s dissent in Obergefell raised this very question, intending to show how radical the majority’s decision could become. But the issue was hard to discuss candidly while same-sex marriage was still pending, because both sides knew that association with plural marriage, a more unpopular cause, could have stymied progress for gay rights. (Opponents of same-sex marriage had reasons to emphasize the association, while supporters had reasons to play it down.) With same-sex marriage on the books, we can now ask whether polyamorous relationships should be next.
