It will be very interesting to see what information the DOJ was getting. If they were using it to dig dirt on GOP opposition during the 2012 elections, it will be the end of them. However, I doubt we will hear of this until after 2014, when they will hit our candidates with an avalanche of allegations from this information.
I’m hearing that it was used to great effect in targeting Obama political adds in the 2012 election. Much like when you get specific adds targeted at you after making a Google search.
