Hahahahahahaha. You are kidding right or do you just know NOTHING about Trump? I have observed him since the 80s. I watched a lot of the apprentice series and I've read and watched a lot more.
You think is was successful? He was DONE until the Mercers swooped in with Bannon and saved his sorry ass. He is a success in the way a cockroach is a success for sure. They got their tax break that is all they wanted except for al the other things he is doing for them, probably via the EPA etc.
Pathological lying is his superpower and it works to a degree however he has had to keep hundreds of small companies instead of a large one. I have worked for three deca-billionares, I have met them, talked to them and have a grasp of their minds I think. I was also an anti-poaching ranger in Africa, believe me I have rubbed shoulders with many powerful men. Trump a teetotaler because his brother drank himself to death sold vodka and sold steaks through the mail and bla such.
I can't bother making this more succinct. He is garbage.
