That’s what Ackerman calls it. Sasha Issenberg explains why the Democrats’ data operation excelled:

If Republicans brought consumer data into politics during Bush’s re-election, Democrats are mastering the techniques that give campaigns the ability to understand what actually moves voters. As a result, Democrats are beginning to engage a wider set of questions about what exactly a campaign is capable of accomplishing in an election year: not just how to modify nonvoters’ behavior to get them to the polls, but what exactly can change someone’s mind outside of the artificial confines of a focus group.

Michael Scherer has more details:

Rather than rely on outside media consultants to decide where ads should run, Messina based his purchases on the massive internal data sets. “We were able to put our target voters through some really complicated modeling, to say, O.K., if Miami-Dade women under 35 are the targets, [here is] how to reach them,” said one official. As a result, the campaign bought ads to air during unconventional programming, like Sons of Anarchy, The Walking Dead and Don’t Trust the B—- in Apt. 23, skirting the traditional route of buying ads next to local news programming. How much more efficient was the Obama campaign of 2012 than 2008 at ad buying? Chicago has a number for that: “On TV we were able to buy 14% more efficiently … to make sure we were talking to our persuadable voters,” the same official said.

The numbers also led the campaign to escort their man down roads not usually taken in the late stages of a presidential campaign. In August, Obama decided to answer questions on the social news website Reddit, which many of the President’s senior aides did not know about. “Why did we put Barack Obama on Reddit?” an official asked rhetorically. “Because a whole bunch of our turnout targets were on Reddit.”
