In addition to the DNC voter file, there are similar lists available commercially.  <a href="http:&#x2F;&#x2F;www.voterlistsonline.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.voterlistsonline.com&#x2F;</a> is run by Aristotle (who tends to have more GOP clients, but is non-partisan).  It has many of the consumer data fields already matched that are discussed in the article.<p>I would not be surprised if Aristotle wasn&#x27;t one of the six customers to which Georgia sent the data.   They have been collecting voter data for years; I worked there for a few months more than 15 year ago, and they already had a nationwide database mostly loaded from 9-track tape.
