In a riveting account based on new documents and interviews with more than 400 sources on both sides of the aisle, award-winning reporter Michael Grunwald reveals the vivid story behind President Obama’s $800 billion stimulus bill, one of the most important and least understood pieces of legislation in the history of the country. Grunwald’s meticulous reporting shows how the stimulus, though reviled on the right and the left, helped prevent a depression while jump-starting the president’s agenda for lasting change. As ambitious and far-reaching as FDR’s New Deal, the Recovery Act is a down payment on the nation’s economic and environmental future, the purest distillation of change in the Obama era.
