Robert Mercer hasn't invested in Donald Trump because he believes in Trump's campaign platform. He preferred Ted Cruz during the campaign, and Ted Cruz was clearly no fan of Donald Trump. Looking at Mercer's historical political giving patterns, Cruz is far more aligned with Mercer's worldview than is Trump.



So, what did Mercer's investment in Trump amount to? He was effectively buying shares in the candidate, and Robert Mercer now owns a sizeable share of the United States Presidency.



Stephen Bannon came from Breitbart News, of which Mercer owns a significant percentage, and Kellyanne Conway came from Mercer's circle of political foundations. And, of course, Mercer's daughter Rebekah represents his interests and his worldview with her presence on the transition committee and her close relationship with Bannon and Conway.
