Harold J. Laski 
American Presidency [PDF ebook] 
An Interpretation

First Published in 1940, The American Presidency is the first full length study of the presidency in action in America to be written by an Englishman. It explains the working of the complicated system over which the President presides and particularly the vexed question of the dual control of foreign relations in the United States. Professor Laski offers a new theory of the place of the presidency in American life and, incidentally, throws light on the inner nature of the other great Anglo-Saxon democracy. His book is more than a formal description. It is essentially a novel interpretation of the greatest elective office in the democratic world. This is a must-read historical reference work for students of politics, American politics, and American history.
