So to take [Jeb] Bush down, Clinton’s team drew up a plan to pump Trump up. Shortly after her kickoff, top aides organized a strategy call, whose agenda included a memo to the Democratic National Committee: “This memo is intended to outline the strategy and goals a potential Hillary Clinton presidential campaign would have regarding the 2016 Republican presidential field,” it read.

“The variety of candidates is a positive here, and many of the lesser known can serve as a cudgel to move the more established candidates further to the right. In this scenario, we don’t want to marginalize the more extreme candidates, but make them more ‘Pied Piper’ candidates who actually represent the mainstream of the Republican Party,” read the memo.

• Ben Carson
