The AP is out with a story on the Romney campaign’s mining of voter data:

Mitt Romney’s success in raising hundreds of millions of dollars in the costliest presidential race ever can be traced in part to a secretive data-mining project that sifts through Americans’ personal information – including their purchasing history and church attendance – to identify new and likely, wealthy donors, The Associated Press has learned.

For the data-mining project, the Republican candidate has quietly employed since at least June a little-known but successful analytics firm that previously performed marketing work for a colleague tied to Bain & Co., the management-consulting firm that Romney once led.

The head of Buxton Co. of Fort Worth, Texas, chief executive Tom Buxton, confirmed to the AP his company’s efforts to help Romney identify rich and previously untapped Republican donors across the country. The Romney campaign declined to discuss on the record its work with Buxton or the project’s overall success. . . .

The effort by Romney appears to be the first example of a political campaign using such extensive data analysis. President Barack Obama’s re-election campaign has long been known as data-savvy, but Romney’s project appears to take a page from the Fortune 500 business world and dig deeper into available consumer data. . . .

Businesses use those kinds of analytics firms to answer key questions for clients, such as where to build a retail store or where to mail pamphlets touting a new product. The analysis doesn’t directly bring in campaign contributions, but it generates the equivalent of sales leads for Romney’s campaign.

The project relies upon a sophisticated analysis by powerful computers of thousands of commercially available, expensive databases that are lawfully bought and sold behind the scenes by corporations, including details about credit accounts, families and children, voter registrations, charitable contributions, property tax records and survey responses. It combines marketing data with what is known in this specialized industry as psychographic information about Americans.
