Trump Presidency, page-9

The real problem with Trump is the uncertainty he has generated.

He is a nihilistic populist political opportunist and above all an insecure, vain, narcissistic megalomaniac. He is saying and doing whatever he thinks will get him elected. He has no idea what what actual agenda or policies he would attempt to implement or how he would implement them, and doesn't care. He has no intention of even attempting act in accordance with anything he has said. In his mind he has nothing to lose by behaving this way. It's get to the White House (if he can) and then figure it all out.

This is the great risk that Trump presents.
