The Bushes aren’t from Georgia, but the powerful Republican clan has become a focal point in a contentious Senate race here as Republican David Perdue trades fire with Democrat Michelle Nunn over her work at the Bush family’s Points of Light foundation. Not surprisingly, former President George H.W. Bush endorsed Perdue, even as Nunn continues highlighting her seven years as CEO of Points of Light, which bills itself as the largest volunteer organization in the world. Now, Perdue finds himself at odds with the Bushes over two statewide ads that suggest the former president’s nonprofit routed money to “terrorists,” a dubious characterization that hinges on a leaked Nunn campaign document that predicted the potential GOP attacks but also called them “distortions.”
