This has been a big, historic week for gay marriage in America. On Saturday, Arkansas issued its first same-sex marriage licenses following a ruling that overturned the state's ban. On Tuesday, an Idaho judge struck down the state's constitutional prohibition against gay unions; the first wedding ceremonies will take place today. And on Wednesday, a federal appeals court heard oral arguments in Bostic v. Schaefer, the highly anticipated challenge to the same-sex-marriage prohibition in Virginia.
The important theme here is that the rapid expansion of gay marriage is being led almost exclusively by judges. Although there were three upheld court rulings in favor of gay unions before summer of 2013, most of the states that allowed gay marriage before the Supreme Court's decision in United States v. Windsor got there with legislation or ballot initiatives. Since Windsor, which struck down the federal ban on gay marriage under the Defense of Marriage Act, there have been nine rulings expanding the definition of marriage. Almost every state where same-sex unions remain illegal now faces a court challenge.
It's not a coincidence that the most liberal, pro-gay areas of the country were the first to embrace legal same-sex unions at the ballot box or the statehouse. New York Governor Andrew Cuomo and state senators in Vermont could afford to cheerlead for marriage equality; their constituents agreed with them. In these areas of the country, people's beliefs eased the way for social change.
