Like the Founding Fathers, Kamala Harris is a child of the Enlightenment. She processes information and gains knowledge through her senses. She trusts experts, not her intuition. She believes the human condition can get better through experimentation, openness to change, and trial and error.
Donald Trump belongs to a much older philosophical tradition. He basically tells us to ignore the evidence of our senses and just trust him, because he is divinely inspired. You could call it medieval, but that would be an insult to the Catholic Church, which worked hard to create an institutional framework to distinguish saints from frauds. In reality, he reminds me more of some bygone Native American tribal leaders than any figure from European history.
