In today's divisive political climate, what happens when people from different parties, with different backgrounds, spend a weekend together, discussing some of America's most polarizing topics? The new documentary series "Divided We Fall: Unity Without Tragedy," aims to bring Americans together. Not necessarily to change any minds, but to find some common ground. The documentary makes its national premiere May 20 on American Public Television. One of the filmmakers behind the project is Tom Cosgrove of Boulder.
