In October 2014, after the National Organization for Marriage encouraged social conservatives to vote for Moulton instead of his openly gay republican opponent, Moulton rejected the support, with a spokesperson saying:
“Seth Moulton fundamentally disagrees with everything NOM stands for and has long said that equality is the civil rights fight of our generation…fighting against groups, like NOM, that deny equality as a basic human right will be a priority of Seth’s in Congress.”
Carrie Rankin, his communication director, noted that Moulton has a gay brother and Moulton has said, “It’s fundamentally wrong that he and I don’t share the same rights just because of who he is.”
