Numerous books have been written about Franklin Roosevelt's effort to "pack" the Supreme Court in 1937. Jeff Shesol's is not only the latest but it ranks as the best. He does an excellent job of tracing the origins of the plan to the legal and constitutional battles over New Deal legislation in the mid-1930s, battles which threatened the very core of Roosevelt's agenda. He describes the cases in clear and accessible prose, bringing both the personalities of the major figures and their ideologies to life and making their struggle in the courts and Congress every bit as dramatic as it was when it unfolded. This is a must-read for anyone interested in well-written history, and an indispensable guide for anyone seeking to learn about the packing plan and its importance in U.S. history.
