After the second presidential debate, Bay Buchanan, a top adviser to Mitt Romney, told reporters the GOP presidential candidate supports leaving the issue of gay marriage up to the states. Romney, she said, is a "strong advocate for the Tenth Amendment" and believes marriage is "a state issue." That constitutes a reversal from his earlier view that he would support an amendment to the constitution defining marriage as between one man and one woman. The significance of Buchanan's remarks were first noted by BuzzFeed's Chris Geidner.
