A ghost has inhabited the Oval Office since 1945-the ghost of Franklin Delano Roosevelt. FDR's formidable presence has cast a large shadow on the occupants of that office in the years since his death, and an appreciation of his continuing influence remains essential to understanding the contemporary presidency. This new edition of In the Shadow of FDR has been updated to examine the presidency of George W. Bush and the first 100 days of the presidency of Barack Obama. The Obama presidency is evidence not just of the continuing relevance of FDR for assessing executive power but also of the salience of FDR's name in party politics and policy formulation.
