"Now, why was Lincoln so great that he overshadows all other national heroes? He really was not a great general like Napoleon or Washington; he was not such a skilful statesman as Gladstone or Frederick the Great; but his supremacy expresses itself altogether in his peculiar moral power and in the greatness of his character."
Trump has no morals, and great weakness of character. He is unwilling, or unable to learn, or to accept responsibility for mistakes. Trump will go down in history as the worst President, in a category of his own, he's so terribly awful.
