Big Data for politicans

Obama: Love him, hate him - you just can't write him down for policies only. If there has been ever any politician to have successfully utilized technology, then it has to be 'Mr.President'. Social media was just one of the weapons in political battle; Big Data is the real deal in Obama's technology arsenal.
“This isn’t just about figuring out who’s going to vote and how they’re going to vote,” Mr. Davis said. “One of the most important things that the candidate does when they use our systems is they actually understand why people are voting for them or why they’re not, and that has the effect of hopefully being able to change policy in a more meaningful and democratic way.”
