At the heart of Master of the Senate is its unprecedented revelation of how legislative power works, how the US Senate works, how Lyndon Johnson on his way to the presidency, mastered both, and how he used his power to pass the first Civil Rights legislation since 1868. Interweaving his narrative of Johnson's political career during the 1950s with brilliantly concise and acute history of the Senate, Caro shows us: How Johnson, employing his guile, his unerring instinct about his colleagues, and his strategic brilliance, became Majority Leader after only one term, and soon the most powerful man in the Senate. How the youngest and greatest Senate leader America has had changed the 'unchangeable' Senate from a loose confederation of sovereign senators to a tightly run legislative machine. How he destroyed the one man who threatened the monetary invincibility of the Texas oil barons who had financed Johnson's rise to power. How Johnson changed the course of Civil Rights in America. This is how political initiatives triumph or fail, how political genius functions. A magnificent work rich in the authority, insight and narrative power that made the Washington Post say of Caro on Johnson: 'At the summit of American historical writing-Proof that we live in the great age of biography.'
