The first legal same-sex marriage in America took place in city hall in Cambridge, Massachusetts, in 2004. President George W. Bush condemned the development, as did Democratic politicians. At the time most Americans agreed—polls showed nearly twice as many opposed gay marriage as supported it. But public support for gay marriage grew. And what began as a judicial decision championed by Birkenstock-wearing liberals became the law of the land ten years ago, on June 26th 2015, when the Supreme Court ruled in Obergefell v Hodges that gay couples have a right to marry.
