FiveThirtyEight's Harry Enten reports that Supreme Court Justice Antonin Scalia has been proven right in predicting--when the court struck down the federal ban on recognizing same-sex marriage--that "'by formally declaring anyone opposed to same-sex marriage an enemy of human decency, the majority arms well every challenger to a state law restricting marriage to its traditional definition.'" Since the ruling in United States v. Windsor, same-sex marriage has comes to states because federal courts have ruled in favor of challengers to bans on same-sex matrimony, Enten concludes.
