After he is "gone" the evil he has done will live long after him. It will be manifested in the waves of white supremacist domestic terrorists. He will be worshipped in their churches and sanctified as a martyr and millions of his adoring worshippers will praise him and pray to him.
An exaggeration? I wish. They are besotted with him. They are infected by his essence. They will get even.
They will never stop believing in him and revenging and retaliating. They ARE HIM. There is no "getting back to normal". His evil will not diminish. It will grow.
Ya know?
