Who’s behind the mysterious “robo-calls” that have spread misleading voter information and sown confusion and frustration among North Carolina residents over the last week? Facing South has confirmed the source of the calls, and the mastermind is Women’s Voices Women Vote, a D.C.-based nonprofit which aims to boost voting among “unmarried women voters.” What’s more, Facing South has learned that the firestorm Women’s Voices has ignited in North Carolina isn’t the group’s first brush with controversy. Women’s Voices’ questionable tactics have spawned thousands of voter complaints in at least 11 states and brought harsh condemnation from some election officials for their secrecy, misleading nature and likely violations of election law.
