There are three words that summarize Trump: Fraudulent Self-Promotion. The is the essence of the man.
He's smart--he went to Penn--but above all he is a venal, corrupt businessman and 24/7 self-promoter. He's a con man, a carnival barker, and a bully. He inherited a significant NY real-estate business from his father plus many millions of dollars. He expanded the business, took on tons of debt, and many times made terrible decisions. He lost all of his Atlantic City casinos, declared bankruptcy 4 times. Until recently, he managed to stay one-step ahead the law, and has been good at strong-arming banks into lending him more and more money until he could get his company stabilized. (But nearly all stopped doing business with him many years ago. He hasn't built anything in more than 20 years because no western banks want anything to do with him. So he's spent the last 20 years trying to con foreign businessmen and banks into doing brand deals with him--they take all the risk building office buildings and condos, the suckers slap the Trump name on the building, and he gets a cut of any profits without taking any risk. A smart con, if it works--but definitely a con.
What he does more than anyone in the history of mankind is promote himself /relentlessly/ and /fraudulently/ as this brilliant and uber-successful person. Nope. Total con job. He is a guy who will say and do ANYTHING to get what he wants--been that way all his life. He is a documented absurd cheater in golf. He lies endlessly to promote himself and to damage opponents--he's a total lowlife. He came down after the Iowa caucus and claimed it was the second time he'd won it. Lie. He claimed after New Hampshire that he'd won the general election in NH in the past. Lie--he lost NH twice, to both Clinton and Biden. Take those examples and multiple then by a billion---blatant, obvious lies throw out every day to make himself look good--and you get the essence of a gangster. His campaign style is to stand up and insult and try to mock his opponents. That's it. A nasty, sinister man. He said yesterday or the day before that Haley supported Obama---lie. This is who he is and what he does. A lowlife and a gangster. Oh, and he's utterly, utterly shameless. We've all seen that.
