There is a great deal to learn in studying the successes and failures of Presidents Kennedy, Nixon, Biden, and Trump, four presidents whose administrations coincided with dramatic societal changes and challenges. This book is a warning that our democratic form of government is in danger of collapsing and being replaced by an authoritarian state. Douglas E. Schoen keenly analyzes the presidencies of Kennedy, Nixon, Biden, and Trump through the lenses of political polarization, election campaigns, their early lives, their changing administrations, the role of fast-changing media, the impact of shifting racial relations, the drama of increasingly divisive immigration issues, and America's evolving defense and foreign policy. Schoen uses these comparative analyses to create a masterful plan to unite America and save our democracy. His important suggestions include political reforms that support equality, improved education, and job training. He advocates for greater access to healthcare and compulsory national service. The plan encourages less partisan and divisive media and encourages the export of American ideals rather than American military power.
