You should look closer at the Trump U findings and the Taj Mahal bankruptcy. The Clown is nothing but a swindler and a con artist. He's not a successful businessman, he's just Carl Icahn's stooge, all the way back to 80s. Trump is just a brand, a frontman. His casinos, golf courses, and other ventures are actually owned by Icahn.
And why is Trump running for POTUS? Because Icahn bet the wrong way on energy a couple years ago. A vote for Trump is actually a vote for higher gas and oil prices. Why else do you think Putin loves him? Low oil prices have almost bankrupted the Russian economy.
