A huge trove of voter data, including personal information and voter profiling data on what’s thought to be every registered US voter dating back more than a decade, has been found on an exposed and unsecured server, ZDNet has learned.

Each record lists a voter’s name, date of birth, home address, phone number, and voter registration details, such as which political party a person is registered with. The data also includes “profiling” information, voter ethnicities and religions, and various other kinds of information pertinent to a voter’s political persuasions and preferences, as modeled by the firms’ data scientists, in order to better target political advertising
