"The current election cycle has also turned to political psychologists, many of which are hired to analyze voter data and then use their findings to develop strategies to increase voter support. Republican presidential nominee Ted Cruz has hired behavioral scientists to gather data of potential voters from consumer habits and Facebook posts and then apply personality and political scores to this data.The personality and political scores then allow the campaign to tailor outreach strategies to particular voters. For instance, pro-gun messages where firearms are used for protection are pitched to the more “neurotic” personalities to play off their fearful attitudes."

LoL!! They have done a superior job during this election don't you think?
