“We are guaranteeing you will reach the right person at the right time and eliminate the waste that you might find in email marketing, certainly in TV advertising,” Eric Laurence, who is in charge of political advertising on Facebook, told National Journal. “That’s really the power of Facebook targeting.”
Campaigns can upload a voter file and Facebook will send targeted ads to those users. For instance, those who have given money to a campaign might be asked to give again, while those who merely clicked on a candidate’s link might be asked for an email address.
“I think most users really have no idea how much information Facebook collects about them or how Facebook is able to infer from even a post to a friend what their political orientation might be,” Marc Rotenberg, the president of the Electronic Privacy Information Center, told The New York Times. “If you’re a Facebook user, Facebook knows everything you’ve said, everything you’ve posted, everything you’ve clicked on.”
