Book excerpt: The Constitution has governed the United States since 1789, but many Americans are not aware of the structural rules that govern the oldest democracy in the world. Important public policy challenges require a knowledgeable, interested citizenry able to address the issues that represent the rich pageantry of American society. Issues such as climate change, national debt, poverty, pandemics, income inequality, and more can be addressed sufficiently if citizens play an active role in their own republic. Collectively, citizens are vulnerable to exploitation and manipulation if we place limits on our individual political knowledge. A more informed, engaged citizenry can best rise to the great policy challenges of contemporary society and beyond. Brian L. Fife provides readers with essential information on all aspects of American politics, showing them how to use political knowledge to shape the future of the republic. Activist citizens are the key to making the United States a more vibrant democracy. Fife equips citizens and would-be citizens with the tools and understanding they need to engage fully in the political process. At the end of each chapter, he analyzes why citizenship matters and how citizens can use that chapter’s material in their own lives. Fife also provides readers with a citizen homework section that presents web links to further explore issues raised in each chapter.
