As David Dayen details, there is a reason Warren’s brand of populism is ascendant in the Democratic Party: She is articulating a coherent, interlocking set of ideas focused on the economic prospects of the middle class, and a broader critique that explains how and why the economy got to this point, with more passion and specificity than anyone else. There is no reason why these groups would stand down from feeding the dream of a Warren presidential run, as long as the mere possibility continues to generate media attention — no matter how far-fetched that possibility appears, and no matter what Warren herself says about it.
