A deeply-reported, firsthand account of how Barack Obama and Hillary Clinton attended to embody two competing visions for the part of the United States in the world–and what that means for the 2016 presidential election. NY Times White House correspondent Tag Landler goes behind the speeches and press conferences, to the problem Room debates and picnic-table lunches, where Obama and Clinton honed their two contending worldviews: his, cautious, inward-looking, suffused with a sense of limits; hers, muscular, positive, unabashedly old-fashioned. Alter Egos is about two ambitious politics archrivals from completely different backgrounds who became partners for a time, trailblazers who talk about a common sense of their traditional destiny but who keep fundamentally different values about how to project American power. With all the sweep of a grand history-and enlivened by an insider’s access and a lot of news-Landler digs deep in to the complicated relationship between both of these leaders and gives us a different method to take into account Obama’s legacy and Clinton’s promise.
