On today’s show, we’ll interview David Madland, a senior fellow at the Center for American Progress and author of “Hollowed Out: Why the Economy Doesn’t Work without a Strong Middle Class,” about what he’ll be looking for in Hillary Clinton’s Detroit speech. Plus, we’ll talk about expectations for retail sales; Arianna Huffington’s decision to leave the Huffington Post; and a U.S. court’s decision to halt the expansion of fast internet in two cities.
