How changing demographics are reshaping the political landscape of America. Clarkston, GA is a small town of 7,500 that has gone from being 90% white in the 1980s to less than 14% white today. In the shadow of Stone Mountain, once a gathering place for Ku Klux Klan cross burnings, today it is home to thousands of refugees from Vietnam, Somalia, Iraq and Bhutan and some 40 other countries.
