"The political action committee founded by John R. Bolton, President Trump’s incoming national security adviser, was one of the earliest customers of Cambridge Analytica...."

"... which it hired specifically to develop psychological profiles of voters with data harvested from tens of millions of Facebook profiles, according to former Cambridge employees and company documents.... The contract broadly describes the services to be delivered by Cambridge as 'behavioral microtargeting with psychographic messaging.'... 'The Bolton PAC was obsessed with how America was becoming limp wristed and spineless and it wanted research and messaging for national security issues,” [said Christopher Wylie, a data expert who was part of the team that founded Cambridge Analytica]. 'That really meant making people more militaristic in their worldview,' he added. 'That’s what they said they wanted, anyway.' Using the psychographic models, Cambridge helped design concepts for advertisements for candidates supported by Mr. Bolton’s PAC.... One advertisement, a video that was posted on YouTube, was aimed at people who scored high for conscientiousness, and were thought to respect hard work and experience. It emphasized Mr. Bolton’s time working for Ronald Reagan and how [a candidate] embodied the spirit and political ethos of the late president."
