No one should be surprised by this type of comment from Eric T.  He is the dimmest of a not particularly bright family and has not really been exposed to real life.

It defies common sense that anyone thinks that his father "the Donald" is smart. His business success has simply been a combination of a huge head start, followed by a pattern of brinksmanship, gall,  ruthlessness, and contempt for others.

His personality flaws of being insecure and thin skinned are unusual to find in a politician and will be his undoing. 

History will look back on the Trump era with scorn and amazement.
