Sounds like you are saying he is politically effective, that's alllll he is! We need to learn it live it or keep losing.
DEFINITION OF A DEMAGOGUE:
“A demagogue or rabble-rouser is a political leader in a democracy who appeals to the emotions, prejudices, and ignorance of the poorer and less-educated classes in order to gain power. Demagogues usually oppose deliberation and advocate immediate, violent action to address a national crisis; they accuse moderate and thoughtful opponents of weakness. Demagogues have appeared in democracies since ancient Athens. They exploit a fundamental weakness in democracy: because ultimate power is held by the people, nothing stops the people from giving that power to someone who appeals to the lowest common denominator of a large segment of the population.”
