evidence: Throughout the Democratic primary, Biden stuck to a more moderate platform, while Sanders, Massachusetts Sen. Elizabeth Warren and much of the rest of the crowded field courted progressives and advocated for broader structural changes. But as the United States faces a growing pandemic and unemployment rates at the highest levels in generations, Biden has been talking more and more about a presidency that approaches Franklin Delano Roosevelt's, with bold progressive ambitions. [...] "The goals of the task force were to move the Biden campaign into as progressive a direction as possible, and I think we did that," Sanders told NPR. "On issue after issue, whether it was education, the economy, health care, climate, immigration, criminal justice, I think there was significant movement on the part of the Biden campaign." [...] Sanders hopes this document will get more progressives excited about the goals, not just the existence, of a Biden administration. "When I talked to Joe a while back, he said that he wants to be the most progressive president since FDR," Sanders said. "Do I believe that Biden believes that now is the time for bold action to protect the working class and lower-income people in this country? Yes, I do believe that's the case."
