Vice presidents occupy a unique and important position, living partway in the spotlight and part in the wings. Of the forty-eight vice presidents who have served the United States, fourteen have become president; eight of these have risen to the Oval Office because of a president’s death or assassination, and one became president after his boss’s resignation. John Nance Garner, FDR’s first vice president, famously said the vice presidency is “not worth a bucket of warm piss” (later cleaned up to “warm spit”). But things have changed dramatically in recent years. In interviews with more than two hundred people, including former vice presidents, their family members, and insiders and confidants of every president since Jimmy Carter, Kate Andersen Brower pulls back the curtain and reveals the sometimes cold, sometimes close, and always complicated relationship between our modern presidents and their vice presidents.
