According to Donald Trump biographer Michael D’Antonio, the president’s talk about having good genes is more than a casual statement.
Trump has a deeply held belief that one’s genetic makeup determines everything from eye color to business success, and he truly believes he was gifted amazing genes by his parents.
Michael D’Antonio claimed the candidate's father, Fred Trump, had taught him that the family’s success was genetic.
He said: “The family subscribes to a racehorse theory of human development.
“They believe that there are superior people and that if you put together the genes of a superior woman and a superior man, you get a superior offspring.”
What D’Antonio describes is the theory of eugenics, and apart from a seemingly small group of followers, it was widely discredited following World War II -- though not before it was used to justify the sterilization of disabled people and other atrocious actions.
During his presidential campaign, Trump regularly pointed to his good genes and superior intellect to prove his suitability for the highest office.
Mr Trump has become notorious for his bravado on the campaign trail and claimed he could solve problems that have plagued policymakers for decades with ease because he is a “smart guy”.
He said: “People are fed up – they are fed up with incompetence, they are fed up with stupid leaders, they are fed up with stupid people.”
At a rally in Washington, D.C. in September 2015, Mr Trump claimed that, if he became president, “we’ll win so much, you’ll get bored with winning”.
And it’s likely the President of the United States meant every word of that claim, because he truly believes that winning is genetic -- and he has the best genes.
