Opponents to same-sex marriage used to whine that the courts had no right to define marriage, only elected legislatures or the people. Then, when some state legislatures granted that right, they claimed that in no instance had the people themselves granted that right.
Now, they've lost that trope. On Tuesday, voters in Maine, Maryland and Washington approved same-sex marriage, joining Connecticut, Iowa, Massachusetts, New Hampshire, New York, Vermont and the District of Columbia.
Soon a majority of Americans will live in states that allow same-sex marriage, and states prohibiting it will be seen, rightly, in the same light as states that once banned interracial marriages.
