Using a “How a Bill Becomes Law” approach, Washington at Work brings to life the modern policy-making process of the United States government through a thought-provoking case study of the 1990 Clean Air Act. Congress, the Presidency, interest groups and the Bureaucracy are examined by following this Act from its inception to a final “product” that was passed into law. In addition, the second edition describes the environmental and political effects of steps that have been taken since 1990 to implement the new law.
