Well, now we know why. Trump's gene pool is sadly lacking and it's still being passed on.

It helps us to make close connections with people, and influences how we behave in a range of situations, from the workplace to a party.
Now scientists say empathy is not just something we develop through our upbringing and life experiences - it is also partly inherited.
A study of 46,000 people found evidence for the first time that genes have a role in how empathetic we are.
And it also found that women are generally more empathetic than men.
Empathy has an important role in our relationships.
It helps us recognise other people's emotions and it guides us to respond appropriately, such as by knowing when someone is upset and wants to be comforted.
It is largely considered to be something we develop through childhood and our life experiences.
But in this new paper, published in the journal Translational Psychiatry , scientists looked to see if how empathetic we are can be traced to our genes.
