Eminent psychologist Dr John Gartner, formerly of Johns Hopkins University School of Medicine, stated that Donald Trump exhibits what is known as malignant narcissism. The term is not a formal diagnosis in modern psychiatric manuals, but it is widely used in psychological discussion to describe an especially destructive cluster of personality traits.
Listen to what this psychologist has to say:

According to Gartner, malignant narcissism is a fusion of narcissism, psychopathy, paranoia and sadism. At its core lies an extreme sense of self-importance and grandiosity. A person displaying these traits often believes themselves uniquely superior, entitled to admiration and beyond the normal rules that govern everyone else. In Trump’s case, Gartner argues that this manifests through relentless self-praise, an obsession with loyalty and a tendency to portray criticism as persecution.
The psychopathic element refers to a profound lack of empathy, remorse, or concern for the harm caused to others. This can lead to manipulative behaviour, habitual dishonesty and a willingness to exploit people or institutions for personal gain. Added to this is paranoia; a worldview in which opponents, journalists, judges, or even former allies are seen not merely as critics but as enemies engaged in plots or conspiracies. Gartner further argues that sadistic tendencies may be visible in the apparent enjoyment of humiliation, public attacks and the sowing of chaos.
The consequences of such a personality profile, if accurate, are potentially severe, particularly when attached to immense political power. Leadership driven by grievance, revenge and self-glorification can destabilise democratic institutions, deepen social division and encourage cult-like loyalty among supporters. Decisions may become less about public interest and more about personal vindication.
That said, Gartner’s remarks remain controversial. Many clinicians point to the Goldwater Rule, the ethical principle discouraging mental health professionals from diagnosing public figures they have not personally examined.
Whether one agrees with Gartner or not, the viral spread of the clip reflects a wider public anxiety: what happens when personality, power and political influence become dangerously entwined?
And don’t forget Farage and co.
