FDR led America through the two greatest crises it faced in the 20th century—the Great Depression and World War II. Crippled by polio, he helped guide the country out of that depression, then after a sneak attack that destroyed its Pacific fleet he lead the nation to victory against dictatorships in both Europe and Asia.
Trump is an clown crippled by egoistic delusion, creating crises, and leading supporters whose self-deception has become the rule rather than the exception.
