President Barack Obama's 2012 re-election campaign proved a landmark moment in political data mining — Obama's team ran non-stop simulations based on poll data and used the information they'd collected about supporters to perfectly time appearances.

"When you go where the money is and you go where people get reached, you have a transformational effect," says former campaign media tracking director Chauncey McLean. "Money creates change."
