The Federal Government in the United States is a government “of the people, by the people, and for the people.” Presidents are elected by popular vote in the nation (filtered through the electoral college), Senators are elected by popular vote in their states, and Representatives are elected by popular vote in their Congressional districts. Cabinet members and agency heads are appointed by the elected president, as are members of the Supreme Court.

But this says nothing about politics. Professor Lauman and Knoke have asked, in this book, how policies were made, in the period 1977-1980, in the areas of energy and health. The question is a very different one from the question of how the positions of president and Congress are filled.
