The Affordable Care Act was meant to bring the US into alignment with every other developed country in offering universal health coverage. Author Jonathan Cohn joins Dr. Josh Sharfstein to talk about how a health care law that has been debated since the 1930s finally gained traction under Obama and insured millions of people with serious health conditions, and yet leaves so much undone. The Affordable Care Act is a story of just how hard policy change in the US can be. Note: You do not have to have read Cohn's book to enjoy this conversation.
