From Merriam-Webster: "a situation in which a public figure (such as a political leader) is deliberately presented to the people of a country as a great person who should be admired and loved". Wikipedia mentions the use of mass media, propaganda, spectacle, etc. "to create an idealized, heroic, and worshipful image of a leader, often through unquestioning flattery and praise". I see nothing there about splitting the party and revenge. Remember these?
While I agree he's far from perfect (at the very least he sanctioned a couple extrajudicial executions and a coup in my home country) he seems to be a loving husband and father, can complete sentences and expose coherent reasoning. He clearly shows signs of a very superior intelligence, never declared bankruptcy (and never bankrupted a casino!) or defrauded investors, nor cheated on every single wife he had (he's still on his first one and she is a keeper).
Maybe. OTOH, a politician can be a huge influence for good. Kennedy's "We chose the Moon" speech influenced generations of engineers and scientists all over the world. JFK was not a good role model and, yet, he managed to bring out the best in a whole lot of people.
Humans are flawed - we can't escape that. Every human has a dark side but, it seems, some humans have a very large one.
