In this, the first full-length, scholarly examination of Martin's career readers will encounter a devoted public servant who often modified his party's extreme stances on domestic matters during the Great Depression and on foreign policy issues leading up to World War II. This political biography effectively illustrates that bipartisanship does not mean abandonment of principles, that kindness, integrity, and gentility are compatible with effective leadership, and that close friendships with members of the opposing party can contribute to a more effective Congress.
