The question of the moment is: If GOP front-runner Donald Trump were to be elected president, what would he do?

At least on the economic side, we recently had glimpses of what could lie ahead. And those fiscal hints have much broader implications, including for U.S. national security.

Trump contends he can run Washington far better by treating the federal government like one of his companies. He has a very particular style as a real-estate developer, and his general approach to business could indeed be applied to fiscal and monetary policy. Any way that you look at what Trump is inclined to do, however, the result could lead to unprecedented disaster on a global scale.
