Yes, but that’s only one piece of the puzzle.
Remember how, back in 2008, 2010 and 2012, Obama sent his campaign workers out unto the field, under the auspices of canvassing, with GPS locaters used to pinpoint as many dwellings as possible, then gather as much data as possible on the occupants?
The Obama folks, usually people living in the neighborhoods they were canvassing, were relentless. I politely declined to provide ANY information at least six times. At the end the neighbor got really agitated with me ... and probably plugged in information on me gathered elsewhere ...
Looking at these things as “databases” really understates what’s going on. In reality they’re probably building a massive data warehouse that contains information culled from all sorts of different sources, not just these 50 state databases. The datamining capability, the ability to cross reference virtually every aspect of an individuals life, is going to be awe inspiring (in an evil genius way, per the article)
