Demagogue, look it up!

https://en.wikipedia.org/wiki/Demagogue

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,[2][3] is a political leader in a democracy who gains popularity by arousing the common people against elites, especially through oratory that whips up the passions of crowds, appealing to emotion by scapegoating out-groups, exaggerating dangers to stoke fears, lying for emotional effect, or other rhetoric that tends to drown out reasoned deliberation and encourage fanatical popularity.[4] Demagogues overturn established norms of political conduct, or promise or threaten to do so.[5]: 32–38 

Demagogues typically choose their words for their emotional effect on the audience, often without regard for factual truth or for potential danger.[23][24] Demagogues are opportunistic, saying whatever will generate controversy and spur public energy. Other demagogues may believe falsehoods they tell.[13]

Many demagogues have found that ridiculing or insulting opponents is a simple way to shut down reasoned deliberation of competing ideas, especially with an unsophisticated audience.

Many demagogues violate standards of decorum outrageously, to show clearly that they are thumbing their noses at the established order and the genteel ways of the upper class, or simply because they enjoy the attention that it brings.

Because factual information reported by the press can undermine a demagogue's claims and standing among followers, modern demagogues have attacked the press intemperately.

Demagogues often appoint people to high office based on personal loyalty without regard to competence for the office—opening up extraordinary avenues for graft and corruption.
