How Robert Mercer exploited America’s populist insurgency. Politics, Presidential candidacy, political influence
By Jane Mayer
During the past decade, Mercer, who is seventy, has funded an array of political projects that helped pave the way for Trump’s rise. Among these efforts was public-opinion research, conducted by Caddell, showing that political conditions in America were increasingly ripe for an outsider candidate to take the White House. Caddell told me that Mercer “is a libertarian—he despises the Republican establishment,” and added, “He thinks that the leaders are corrupt crooks, and that they’ve ruined the country.”

Trump greeted Caddell warmly in North Charleston, and after giving a speech he conferred privately with him, in an area reserved for V.I.P.s and for White House officials, including Stephen Bannon, the President’s top strategist, and Jared Kushner, Trump’s son-in-law. Caddell is well known to this inner circle. He first met Trump in the eighties. (“People said he was just a clown,” Caddell said. “But I’ve learned that you should always pay attention to successful ‘clowns.’ ”) Caddell shared the research he did for Mercer with Trump and others in the campaign, including Bannon, with whom he has partnered on numerous projects.
