The DNC operation which serves as a de facto arm of the Obama campaign.
From James O’Keefe at the Project Veritas website:
Project Veritas has released a new investigation that exposes Obama campaign workers, including a Regional Field Director at Organizing for America (OFA), engaged in election fraud.
According to James O’Keefe, “These individuals showed no concern whatsoever when our investigators declared their intention to vote multiple times for President Obama. In fact, they were happy to help, even going so far as to provide the forms necessary to commit the fraud and offering advice on how to avoid getting caught.”…
This latest footage was gathered over several weeks in Texas and New Jersey. It shows Obama campaign workers, including Organizing for America Regional Field Director Stephanie Caballero, providing material assistance to individuals who state explicitly that they intend to commit election fraud.
There is no doubt that these workers know exactly what they are doing.
