We’re all used to hearing about Red America and Blue America, but what if the country’s real political divide is actually split along a four way fracture? On this edition of KCBS In Depth we speak with journalist and author George Packer about his new book, “Last Best Hope: America in Crisis and Renewal,” which seeks to map out the lines of political division that run through the nation as a first step toward patching it all back together.
