This is a must-read. It describes how the Democrats have very successfully used technology to get out the vote, perhaps decisively, from far-left constituents who otherwise would not have voted. The key points are 1) an understanding that if a party can identify members of its base it is much cheaper to convince them to vote for the party’s candidates than it is to convince uncommitted moderates, 2) effective cooperation among Democratic operatives and politicians at all levels to gather and share contact and demographic data about as many voters as possible, and 3) the application of modern analysis techniques to those data, and the subsequent targeting of the most-likely Democratic voters for GOTV efforts. This is part of how Obama got himself reelected in 2012 despite his exceptionally weak record. Meanwhile Republicans have futilely attempted, at great cost in money and in support from members of their conservative base, to win over indecisive moderates.
