What is the author's tone in Franklin D. Roosevelt and the New Deal, 1932-1940 by William E. Leuchtenburg?

The tone of the book is objective. The author does not try to impose his own views on the reader or make moral judgments. He basically tells the story of what happened in terms of the problems, the personalities, and the programs. There is no attempt to "paint" people in any kind of light or to lay the blame on any particular individual. The author does not blame the Republicans or the Democrats for the situation. He just presents the facts as they occurred.
