本書は、弾劾訴追が可能な犯罪の範囲を定義し、職務上の不正行為に対処するために憲法がどのように代替手続きと制裁を規定しているかを説明します。また、リンカーンの暗殺後、その寛大な南部再建策を継いで共和党の反感を買い、米国大統領として初の弾劾裁判にかけられたアンドリュー・ジョンソン（在任1865-69年）やビル・クリントン（在任1993-2001年）が有罪判決に至らなかった理由や、連邦裁判官の弾劾が、このプロセスにおける法と政治をどのように浮かび上がらせるかを説明します。
憲法学の専門家で、クリントン大統領に対する弾劾手続きにおける唯一の共同証人だったマイケル・J・ゲルハルトが、弾劾の意味、起源、慣行、限界、代替案から、今日の政治における役割までをわかりやすく解説しており、弾劾について一歩踏み込んで考えてみたい人に最適な入門書になっています。

Impeachment: What Everyone Needs to Know® is the step back and deep reflection on the law of impeachment that everyone needs now. Written in an accessible and lively question-and-answer format, it offers a timely explanation of the impeachment process from its very meaning to its role in politics today. 
    
The book defines the scope of impeachable offenses, and how the Constitution provides alternative procedures and sanctions for addressing misconduct in office. It explains why the only two presidential impeachments, those of Andrew Johnson and Bill Clinton, failed to lead to conviction, and how the impeachments of federal judges illuminate the law and politics of the process. 
    
As a legal expert and the only joint witness in the impeachment proceedings against President Clinton, author Michael J. Gerhardt also explores a question frequently asked-will Donald Trump be impeached? This book does not take a side in the debate over the possible impeachment of the president; instead, it is a primer for anyone eager to learn about impeachment's origins, practices, limitations, and alternatives.
