"Insofar as there was confusion about what Windsor meant at the time it was decided, the lower courts across the country have now effectively settled it. A survey of publicly available opinions shows that in the eight months since Windsor, 18 court decisions have addressed an issue of equality based on sexual orientation. And in those 18 cases, equality has won every single time. In other words, not a single court has agreed with Chief Justice Roberts that Windsor is merely about state versus federal power. Instead, each has used Windsor exactly as Justice Scalia 'warned' — as a powerful precedent for equality."
