Identifying the voter
Catalist is a privately financed large-scale political data-mining shop and has documented the political activity of every American 18 and older: where they registered to vote, how strongly they identify with a given party, what issues cause them to sign petitions or make donations. Catalist offers progressive organizations access to a national database of voting-age individuals in the United States. Their databases are fed by 450 commercially and privately available data layers as well as firsthand info collected by the campaigns. Candidates are then able to target voters from ever-smaller niches. Not just blue-collar white males, but married, home-owning white males with a high school diploma and a gun in the household. Not just Native Americans, but Native Americans earning more than $80,000 who recently registered to vote.
