Elizabeth Warren is the founder of the Consumer Financial Protection Bureau, the senior senator from Massachusetts, and the author of the new book, “This Fight Is Our Fight: The Battle to Save America's Middle Class.”You might have heard of her.Warren is also one of the Democrats most capable of defining the Democratic Party’s soul and message in a post-Trump era. In her book, she says she had at least one big disagreement with President Obama — a disagreement that speaks to the direction she wants to lead the party. Obama told Americans, “the system isn’t as rigged as you think.”"No, President Obama,” Warren replies, "the system is as rigged as we think. In fact, it’s worse than most Americans realize.”In this interview, we go deep into Warren’s view on how, where, and why the system is rigged — as well as what can be done about it. We also talk about whether fighting Trump requires matching his tone and tactics, how complex policies and processes create space for special interests to take over, and why Trump’s abandonment of economic populism hasn’t affected his support among his voters.Warren is an able, thoughtful advocate for one of the Democratic Party’s possible futures: becoming a party that represents the economic populism Trump claimed to champion, but quickly abandoned. But as she’s the first to admit, that won’t be easy.Books:“Evicted," by Matthew Desmond"Two Dollars a Day," by Kathryn Edin “The Little Engine that Could," by Watty Piper Learn more about your ad choices.
