Book excerpt: Landmark political confrontations between sitting presidents and powerful senators have occurred throughout American history--some have shaped the nation. This book takes an in-depth look at seven of those major "Washington wars," including the personal rivalries that spawned each one, the strategies and events that transpired as a result, and the aftermaths and impacts on the country. Neither compromise nor surrender were considered in these intense debates, which left scars on the national psyche. Each episode could be worthy of a historical narrative all its own but considered together they illustrate the long and bitter history of democratic warfare between the leaders and branches of government at either end of Pennsylvania Avenue.
