Why Elizabeth Warren's new book doesn't read like presidential prologue
...But the "will you run" question likely misses the point; she almost certainly won't. Those who doubt her disclaimers of interest should examine how generously the book treats leading Democrats, starting with the woman she presumably would have to defeat, Hillary Rodham Clinton.
This is not a score-settling book at least not with fellow Democrats nor one designed to lay the groundwork for an insurgent campaign. It offers more earnestness than revelation.
Warren does criticize "the president's team" for worrying too much about bankers and not enough about average Americans during the financial crisis, but only in the abstract. When she names names at least of fellow Democrats it is usually for praise.
Take former Treasury Secretary Timothy Geithner, for example. Warren and he had a famously fraught relationship. But the only example of specific disagreement she provides here comes in an anecdote about her chiding Geithner for not wearing a seat belt while en route to dinner. On more substantive matters, she says Geithner "had our back" during creation of the Consumer Financial Protection Bureau, the achievement that catapulted her to the Senate. ... That combination, a crusading passion wrapped with academic rigor and covered by grandmotherly reassurance has helped give Warren the rarified status of having an entire wing of the party named for her. By the evidence of this book, she won't parlay that prominence into a run for the 2016 nomination, but she'll do whatever she can to influence those who do.
