Randolph's account of Bloomberg's life and time reads almost like a novel, a quintessentially American story. She explains the "machine" he invented that gave and continues to give instant access to an infinite amount of information to bankers and investors on how, what, and where to invest, and how it changed the financial universe. Randolph recounts one day not long ago when the Bloomberg machine briefly blipped and the whole world's financial marketplace came to a halt. Randolph recounts Mayor Bloomberg's vigorous approach to New York city's care--including his attempts at education reform, contract control, anti-smoking and anti-obesity campaigns, green climate control, and his political adventures with both aides and opponents. After a surprising third term as Mayor, Bloomberg returned to his business and doubles its already tremendous worth. The chapter that describes this is one of the most revealing of his temperament and energy and vision as well as how he spends his "private" time--private but convivial. Bloomberg's philanthropies are education, anti-NRA, and supporting a cleaner environment. He is a moderate liberal in a time when that quality holds the future of the Democratic Party and the country to account.
