Preface

Why this book exists

Most American Government textbooks have a credibility problem with their readers. The standard textbook — the one assigned in the required college course, the one that costs the student $150 to $300, the one that arrives in the fall and is forgotten by spring — describes how American government is supposed to work. Three branches. Checks and balances. A bill becomes a law. The people vote. The system, in this telling, is a smoothly functioning machine designed by wise people in 1787 and operating more or less as designed today.

The student looks up from the textbook and sees something different. They see a Congress that cannot pass a budget on time. They see a Supreme Court whose composition was determined by which seats happened to come open while which party controlled the Senate. They see campaigns funded by donors most voters have never heard of, in districts drawn by politicians to choose their voters. They see a presidency that has steadily accumulated powers no one in 1787 imagined any executive should have. They see partisan media ecosystems in which their relatives no longer share basic facts.

The disconnect between textbook and reality is the civics gap. And the civics gap, more than any single political controversy, is the thing this book exists to address.

The standard response to the civics gap is one of two failures. The first is to keep teaching the idealized version and hope students don't notice — to produce graduates who can name the three branches but cannot read a campaign-finance disclosure, who memorized "checks and balances" for the exam but cannot explain why the filibuster lets 41 senators block legislation supported by 80 percent of voters. The second failure is the cynical one: to teach American government as a story of corruption, capture, and inevitable decline, producing graduates who understand the dysfunctions perfectly and have concluded that participation is futile.

Both failures lead to the same place. Civic disengagement. Lower turnout. Less attention. A shrinking pool of citizens who participate in the system, leaving more space for the ones who already do.

This book takes a third path. It is honest about institutional dysfunction without being cynical. It treats gerrymandering, money in politics, polarization, and the gap between constitutional design and actual practice as central themes — not as sidebar boxes that complicate an otherwise tidy story. And it argues, throughout, that real understanding of how the system works is the only durable foundation for real civic engagement. You cannot fix what you do not understand. You cannot decide whether the system is worth defending — or worth reforming, or worth rebuilding — until you have looked at it clearly.

What this book commits to

Six commitments shape every chapter.

Honesty about dysfunction. When we describe the Senate, we describe its design and we describe what the filibuster has become. When we describe the Supreme Court, we describe judicial review and we describe how a justice's seat depends on which party held the Senate the year a vacancy opened. When we describe the budget, we describe authorization and appropriations and we describe the continuing-resolution treadmill. Frustration with the system, we argue, is the first sign that you are paying attention.

Data over assertion. Real numbers from real sources — the Federal Election Commission, OpenSecrets, the Census, Pew, the American National Election Studies, GovTrack, 270toWin. We cite sources, we say "data as of" with explicit dates, and we teach the reader how to read political data rather than asking them to take our word for it. Appendix F (How to Read a Poll) and Appendix G (How to Read Election Results) are reference tools you will return to.

Behavioral science integrated. Why people vote, why people don't, how cognitive biases shape political judgment, how media exposure changes what people believe. American Government is a humanities-and-social-sciences book; the social-science half is real.

Ideological balance. This is the commitment that requires the most discipline. The book is written to be adopted by professors at Berkeley and Liberty University. By community-college instructors in Mississippi and state-university instructors in Massachusetts. By instructors who voted for Trump in 2024 and instructors who voted against him. Every contested values question presents the strongest version of each side's argument with genuine charity. We never strawman. We pair examples by party — Republican gerrymandering and Democratic gerrymandering, Republican constitutional hardball and Democratic constitutional hardball, conservative interest groups and progressive ones. On empirical questions, we follow the evidence; on normative questions, we present the disagreement.

We expect that some readers will encounter passages that feel unfair to their side. If readers across the political spectrum feel that equally — if a left-leaning student finds the chapter on civil rights insufficiently committed and a right-leaning student finds the same chapter ideologically slanted — the book has done its job. Steel-manning the position you don't hold is not symmetry for its own sake. It is the discipline that makes the book usable across the political spectrum, and the discipline that makes a reader's eventual conclusions their own rather than ours.

Institutional analysis. Good people in badly designed institutions produce bad outcomes; bad people in well-designed institutions are constrained. Institutional reform often matters more than which individuals hold office. This is a perspective with both conservative and progressive resonances, and the book treats it as the analytic core of political science rather than as a partisan claim.

Currency. The 2024 presidential election. The post-January-6 landscape. The Roberts Court's transformation, including Dobbs (2022) and the major-questions doctrine. Artificial intelligence and elections. Social-media regulation. The 119th Congress. We do not pretend that American government in 2026 is the American government of 1995, or of 2015, or even of 2019. The book will need updating; that is what an open-source repository is for.

Who this book is for

The primary audience is the student taking the required college course in American Government — required at most American universities, mandated by law for graduation in many states. This is the largest single college-course audience for any textbook in the country, and it is the audience the book is designed for.

The secondary audiences are the AP Government student preparing for the College Board exam (Path 📗 in the next chapter); the new citizen studying American governance; the international student trying to understand a political system that looks bewildering from outside; the community-college student fulfilling a civics requirement; and the general reader — the person who watches the news, votes when they remember to, and has a creeping suspicion that they don't quite understand what they are watching.

What you will get out of this book, if you read the whole thing, is the ability to do specific things you probably cannot do now. Read a member of Congress's voting record. Trace a campaign-finance dollar from donor to ad. Recognize a gerrymandered district. Tell the difference between a law, a regulation, an executive order, and a court opinion. Read a Supreme Court decision and identify what was actually decided. Interpret a poll's methodology. Recognize the difference between empirical claims that are settled and contested values questions that are not. Plan civic engagement that has a realistic theory of change.

You will also have produced, by the final chapter, a 25-to-35-page Democracy Audit of a real congressional district — an analytical profile of real American democracy in action, including its strengths and its dysfunctions. Civic engagement as the assignment.

On the voice of this book

The voice is that of a veteran political scientist who loves the Constitution, respects the institutions, and is honest about where they are failing. Authoritative-approachable. Never cynical. Never naïve. Analytical.

What you will not find: cheerleader prose telling you that American democracy is the greatest in human history. What you will also not find: contemptuous prose telling you that American democracy is a sham and the deck is hopelessly stacked. Both stances are evasions. The truth — the analyzable truth, the truth that political science has tools to investigate — is more interesting than either.

The book does have a perspective. The Constitution was designed for disagreement, by people who expected it; the system is supposed to be slow and frustrating; reform is hard and sometimes important; participation matters. These are arguments the book makes and defends. They are not partisan arguments. A reader can accept all of them and vote in any direction.

The contributing pathway

Any single textbook gets things wrong. Some claims will not survive new evidence. Some examples will date. Some balance calls will look, in five years, like the book leaned in a direction we did not intend. Some readers — including many of the smartest readers — will find passages where we have failed at the steel-manning we promise.

This is why the book is open source under CC-BY-SA-4.0. The repository accepts pull requests. We invite three categories of contribution especially: corrections of factual errors, updates to dated examples and statistics, and balance corrections in either ideological direction. The CONTRIBUTING file describes the process. Significant pedagogical changes get reviewed by editors of a different political orientation than the contributor.

The book belongs to everyone who teaches from it, learns from it, and improves it.

A case for civic engagement

You can read this book and disagree with us about almost everything and still find the conclusion of the final chapter persuasive. The conclusion does not depend on any partisan position. It is this:

Power flows to those who show up. The American system was designed to be responsive to organized, informed, persistent pressure, and indifferent to disorganized, uninformed pressure. Voting, organizing, contacting representatives, attending public meetings, running for local office, paying sustained attention to the institutions that affect your life — these are the mechanisms of democratic power in the system the Founders designed. They are not always sufficient. They are, in this system, mostly necessary.

The people who feel most powerless in American politics often participate least. That is not an accident, and reversing it is the work of citizenship.

Whatever you conclude about the questions in this book — about the role of the federal government, about the proper interpretation of the Constitution, about the policies the country should pursue, about the reforms it needs — we hope you will conclude them on the basis of better information than you had when you opened it, and we hope you will act on them.

Welcome to American Government.
