Robert Caro on Lyndon Johnson's Passage of Power

Robert Caro talks about The Passage of Power, book four of his monumental biography of Lyndon Johnson. It follows Johnson through both the most frustrating and the most successful periods of his career—1958 to1964, when traded his powerful position as Senate Majority Leader for what became the powerlessness of the vice presidency in an administration that didn’t trust him, and then had the presidency thrust upon him when President Kennedy was assassinated.
