Donald Trump is full of braggadocio about his business skills, but the truth is that he's a big-time business loser.

Donald Trump hasn’t served a day in public office. He doesn’t know a thing about policy. He has never studied law or served in the military.

His only asserted qualification for the U.S. presidency is that he’s a successful businessman who will make “the best deals.” But Trump’s self-proclaimed business acumen is just another lie.

The exposure of his grand fallacy leaves us with this: The Republican candidate has literally zero qualifications for the office he seeks.
