How Public Opinion Shapes American Politics This book tracks movement in American public opinion. It examines moods for public policy that cycle over decades. It looks at shorter term movements as the public approves or disapproves politicians, trusts or distrusts government. It is distinctive in that it focuses always on locating the unobserved true opinion that lies beneath, turning away from the superficial polls by which we come to know the real thing. It argues that public opinion is decisive in American politics and it locates the citizens who produce this influential change as a quite small subset of the American electorate.
