A political leader who seeks support by appealing to the desires and prejudices of ordinary people rather than by using rational argument. “a gifted demagogue with particular skill in manipulating the press”
What is an example of a demagogue?
Modern demagogues include Adolf Hitler, Benito Mussolini, Huey Long, Father Coughlin, and Senator Joseph McCarthy, all of whom built mass followings the same way that Cleon did: by exciting the passions of the mob against the moderate, thoughtful customs of the aristocratic elites of their times.
Donald Trump clearly meets the definition. Trump is the 21st century version of McCarthy. It was Joseph Welch finally asked the question of McCarthy: “Have you no decency, sir?” Unfortunately Donald Trump has no decency.
