Donald Trump won millions of followers and, perhaps, the presidency with his blunt and entertaining speeches. So it was probably inevitable that Stephen Bannon, the powerful White House chief strategist who likes to invoke the lessons of history, would compare Trump to an oratorical legend from the past.On Thursday, Bannon told a packed crowd at CPAC, the annual conservative conference, that Trump, only a day before the president gave remarks at the same venue, is “probably the greatest public speaker in those large arenas since William Jennings Bryan.”Bryan, like Trump, did excel in front of mass audiences and often bashed the elites of his day.
