It was all published by WikiLeaks so it would be kind of dumb to waste time hacking for the info.
I refer to the time before Wikileaks and right after the first Wiki revelations. A number of geeks from kids to techie engineers around the country are always exploring for forbidden data fruit. The Dem data was so sloppily protected that it is good bet that much of this stuff had already been hacked. While it was all dripping out there were claims from various sources that they had done it, too.
