I use the statewide voter database most workdays. Electoral campaigns study them intently and have done so for decades, because Alaska has sold that database for decades, as I imagine most states do, because lawmakers need (or want) their state's voter data for their reelection campaigns. This is nothing new. I remember being surprised when I first learned the state sold their dB, but now it seems normal. You can buy the fishing license dB from the state, too. For at least 13 yrs that I know of, geeks have been adding Big Data to the voter lists they bought from states. Corporations also use enhanced voter dBs--to sell stuff, ideas or plans. If I wanted to build a pipeline near you, I'd want to know your and your neighbors' party affiliation and voting frequency...to help me tailor the mailer I'm going to send to you. Such use is nothing new. What's new is social media and its ubiquitous voluntary secession of privacy. Was Zuckerberg right 1/10/10: privacy is dead; long live data?
