“Trump is caught in a box which keeps getting smaller,” says George Conway, a Republican lawyer who is married to Kellyanne Conway, Trump’s senior counsellor. “In my view he is a sociopath and a malignant narcissist. When a person suffering from these disorders feels the world closing in on them, their tendencies get worse. They lash out and fantasise and lose any ability to think rationally.” Conway is known for taunting Trump on Twitter (to great effect, it should be added: Trump often retaliates). Yet without exception, everyone I interviewed, including the most ardent Trump loyalists, made a similar point to Conway. Trump is deaf to advice, said one. He is his own worst enemy, said another. He only listens to family, said a third. He is mentally imbalanced, said a fourth. America, in other words, should brace itself for a turbulent six months ahead – with no assurance of a safe landing.
