As a presidential candidate, Donald Trump specializes in overturning conventional wisdom. Before 2016, it was generally assumed that a presidential candidate needed to be, you know, presidential. But Trump has somehow come within striking distance of the Republican nomination despite insulting large portions of the electorate, buying scant campaign ads, failing to present any coherent policy proposals and being despised by his own party’s establishment. Trump has defied the inherited understanding of generations of pundits, strategists and politicians in his unprecedented bid for the White House. Perhaps the most remarkable bit of conventional wisdom that Trump has thus far disproven is the theory that a Republican presidential candidate can’t succeed without being on good terms with Fox News. “Fox News is the uncontested gatekeeper for Republican politics and Republican politicians,” declared MSNBC’s Rachel Maddow in 2011.
