This won't go anywhere. The thing about Trump is that he's good at starting businesses, but he's a horrible manager. Most of his business ventures have resulted in failure, or him making concessions to his partners, investors, and creditors. His real strength lies in being able to negotiate and bullshit people into trusting him with their money.
Maybe those qualities are integral to a politician, but Trump is a very poor decision maker. If he does run, his opponents will hammer away at him on his inability to effectivley manage. If I wanted to see a real estate tycoon as president, I would rather it be Steve Wynn.
