TFG has no capacity to trust and so is incapable of trustworthiness.
He demands loyalty, but is himself disloyal.
His schtick only works on the people eager to see him as a self-fulfilling prophecy...which has never actually paid off for them.
There is a lot that is politically actionable there. TFG is thriving on some kind of mystique. He is the martyr-bully, which makes him difficult to target.
Difficult, but far from impossible.
