Obama Campaign Advisers Say They Used Facebook Data Properly
In most cases, Obama supporters who signed on to the campaign's mailing list were asked to authorize the campaign's Facebook app, allowing it to access certain aspects of their profile, including their posts, likes, photos, demographics and similar data from their Facebook friends. The Obama data was used in voter turnout efforts, with a focus on young voters in key battleground states, and former campaign officials said the data was kept secure and not sold to or acquired from third parties.
