Like It Or Not, Political Campaigns Are Using Facebook To Target You

Some of the most important real estate in presidential politics is actually right in front of your nose. Or under your thumbs -- it really depends on how you log onto Facebook. The social network is now a key place for campaigns to advertise. One reason for that: It's getting easier and easier for campaigns to target those ads to very specific, tailor-made audiences.

"This is our hub of communication," explained Ken Dawson, who heads digital strategies for Ben Carson's presidential campaign. "We really see it as the heart of our campaign." Carson's Facebook page has more than 4 million followers, more than any other presidential campaign. It's a constant stream of posts, videos and chats with the candidate. Aside from that never-ending flow of content, the campaign is running scores and scores of advertisements that appear in Facebook users' news feeds. In mid-October, the campaign was juggling 240 different advertisements. Nearly every single one was targeted to a different subset of voters.
