Query: Shallow Work

Considering the depth of Miller's larger works of individual biographies, this book disappoints. Miller skims lightly over each of these "worst" presidential lives, presenting only the facts and opinions which support his premise. Better, more thoughtful analysis is available from many sources. In particular, readers might try Robert Gilbert's "The Mortal Presidency" (Harper Collins, 1992) for more human treatment of Calvin Coolidge's deep depression, and Maxim Armbruster's "The Presidents of the United States" (Horizon, 1960) -- arguably the best collection of essays written on the presidents -- for a more objective view of Andrew Johnson's character qualities.
