The American presidential election has been dominated over recent days by speculation about the mental fitness of the two main candidates. First, Donald Trump has picked up on a stray remark by Hillary Clinton that she had "short-circuited" a process over her emails when she was Secretary of State so as to suggest that "she wasn't all there". On the other side, and perhaps with rather more substance, there is an increasing chorus of voices, including a number from the Republicans themselves, concerned that Trump is "unfit to be President".
Of even more immediate concern to the Republicans, however, must be the growing evidence that Trump is not only not fit to sit in the Oval Office - he's not even fit to be a candidate. What's more, his deficiencies in this regard are likely to be increasingly exposed the longer the campaign goes on.
It is not so much a case of mental illness as of personality type. It is clear that Trump has a very unusual personality, perhaps best described as narcissistic. Those with this kind of personality are entirely self-absorbed. They establish an image of themselves that is often at variance with reality and they use all their energies to try to build and conform to that image. They have no regard or concern for others, except to the extent that they support the image.
The narcissist goes to extreme lengths to feed his ego. He not only welcomes but demands flattery. He is prepared to embellish the truth and to invent stories that show him in a good light. He invents and endlessly repeats complimentary remarks made about him by others, and if others do not do this in sufficient numbers, he will do so himself. He insists on being seen as successful, rich and a great lover, even if the facts do not support such opinions.
