<p>In a new book, a niece of President Donald Trump applies her training in psychology to conclude that the president likely suffers from narcissism and other clinical disorders - and was boosted to success by a father who fueled those traits.</p>.<p>In <em>Too Much and Never Enough: How My Family Created the World's Most Dangerous Man</em>, Mary Trump writes of a "malignantly dysfunctional family" dominated by a patriarch, Fred Trump, who showed little interest in his five children other than grooming an heir for his real-estate business.</p>.<p>Ultimately, he settled on Donald, she wrote, deciding that his second son's "arrogance and bullying" would come in handy at the office, and encouraged it.</p>.<p>"He short-circuited Donald's ability to develop and experience the entire spectrum of human emotion," Trump writes. "Donald requires division. It is the only way he knows how to survive - my grandfather ensured that decades ago when he turned his children against each other."</p>.<p>The book, due out next Tuesday, is the first Trump biography written by a family member. The president's brother Robert has tried unsuccessfully, so far, to block its publication.
