The receptivity of the masses is very limited, their intelligence is small, but their power of forgetting is enormous. In consequence of these facts, all effective propaganda must be limited to a very few points and must harp on these in slogans until the last member of the public understands what you want him to understand by your slogan.
-Adolf Hitler in Mein Kampf, Volume One, Chapter Six: “War Propaganda”
Donald Trump is a marketing genius. Trump knows you have about 7 seconds of somebody’s attention. What did Trump do? For a year and a half he repeated the same things over and over and over and over. “Make American Great Again”, “drain the swamp”, “crooked politicians” and other sticky slogans were drilled in people’s mind. And yet we don’t have a single clue how he is going to make America great. Trump won the election with a vocabulary of about twenty words (Loser, winner, huge, rich etc…) Anger and emotions blinded the Americans.
