Senator Warren's example of a proud progressive populist

See this EJ Dionne piece. He reviews Warren's book and notes that she is proud to be who and what she is and makes no bones about it. And that she has a gift for explaining things, i.e., framing the issues in progressive populist terms that resonate with the majority. She is not anti-business but puts it in the context of the social contract that makes business successful, like infrastructure and education. To anti-government proponents she replies that we need police forces, firefighters, food and air safety inspectors to protect us, keep us safe. This is the way it's done to win elections and enact progressive policy. Instead of running to some mythical middle the progressives should take note and wear their agenda proudly and run with it strongly in the coming election cycle.
