CHAPEL HILL — It’s been one year since North Carolina approved Amendment 1—the law that defined marriage solely as a union between a man and a woman.

Out of more than 2 million votes counted from the May 8, 2012 referendum, supporters of the ban led opponents by a 61 percent-39 percent margin—that’s according to figures from the State Board of Elections reported by CNN.

The amendment altered North Carolina’s constitution to say that “marriage between one man and one woman is the only domestic legal union that shall be valid or recognized in this state.”
