Demagogue
From Wikipedia, the free encyclopedia
A demagogue /ˈdɛməɡɒɡ/ (from Greek δημαγωγός, a popular leader, a leader of a mob, from δῆμος, people, populace, the commons + ἀγωγός leading, leader)[1] or rabble-rouser is a leader in a democracy who gains popularity by exploiting prejudice and ignorance among the common people, whipping up the passions of the crowd and shutting down reasoned deliberation.[1][2][3][4] Demagogues overturn established customs of political conduct, or promise or threaten to do so.
Demagogues have appeared in democracies since ancient Athens. They exploit a fundamental weakness in democracy: because ultimate power is held by the people, it is possible for the people to give that power to someone who appeals to the lowest common denominator of a large segment of the population.[5] Demagogues usually advocate immediate, forceful action to address a national crisis while accusing moderate and thoughtful opponents of weakness or disloyalty.
