The Washington Post has an interesting report on the Obama campaign’s voter database which pairs voting records with political donation histories and vast amounts of personal but publicly available consumer data.
“Campaign workers added far more detail through a broad range of voter contacts — in person, on the phone, over e-mail or through visits to the campaign’s Web site. Those who used its Facebook app, for example, had their files updated with lists of their Facebook friends along with scores measuring the intensity of those relationships and whether they lived in swing states. If their last names seemed Hispanic, a key target group for the campaign, the database recorded that, too.”
“To maintain their advantage, Democrats say they must guard against the propensity of political data to deteriorate in off years, when funding and attention dwindles, while navigating the inevitable intra-party squabbles over who gets access now that the unifying forces of a billion-dollar presidential campaign are gone.”
