But since this billboard is the brainchild of alt-right guru Roger Stone we should look at it as Trump's most rabid followers will.
Trump as Superman is a reference to Friedrich Nietzsche's Ubermensch as interpreted by Alfred Baeumler.
I teach you the overman. Man is something that shall be overcome. What have you done to overcome him? ~ Nietzsche, Thus Spoke ZarathustraIt is the vision of a strongman who will replace the petty nihilism of democracy and limitations of modern morality with a God-Man. It is a strongman devoid of the weaknesses of conscience, charity, or compassion willing and able to do those things lesser men once considered evil.
The foundations of Christian morality -- religious individualism, a guilty conscience, meekness, concern for the eternal salvation of the soul -- all are absolutely foreign to Nietzsche. ~ Baeumler (1937)
