"New York Times White House correspondent Mark Landler goes behind the speeches and press conferences, to the Situation Room debates and picnic-table lunches, where Obama and Clinton honed their two competing worldviews: his, cautious, inward-looking, suffused with a sense of limits; hers, muscular, optimistic, unabashedly old-fashioned. Alter Egos is about two ambitious political archrivals from very different backgrounds who became partners for a time, trailblazers who share a common sense of their historical destiny but who hold fundamentally different beliefs about how to project American power. With all the sweep of a grand history...and enlivened by an insider's access and plenty of news...Landler digs deep into the complex relationship between these two leaders and gives us a different way to think about Obama's legacy and Clinton's promise"-- Provided by publisher.
