Wylie says that slogans like “drain the swamp”, used frequently over the course of the Trump campaign, was among those tested by Cambridge Analytica in 2014 — well before the Trump campaign was even in existence.

“The company learned that were segments of the population that responded to messages like ‘drain the swamp’ or images of walls or indeed paranoia about the deep state that weren’t necessarily reflected in mainstream polling or mainstream political discourse that Steve Bannon was interested in to help build his movement,” Wylie told lawmakers.

Wylie said in his testimony that Bannon “is a follower of the Breitbart Doctrine, which posits that politics flows downstream from culture. Therefore, Mr. Bannon sees cultural warfare as the means to create enduring change in American politics.”

…Wylie said that under Bannon’s leadership at Cambridge Anlaytica, U.S. clients could request testing voter suppression efforts in their contracts.
