Hillary on the air in SC

According to an AP story today by Meg Kinnard, Hillary Clinton's campaign will launch its first radio ad in South Carolina, and she harks to education in the short spot. Her message includes a reference to the state's poor rural school districts along Interstate 95, dubbed the Corridor of Shame and chronicled in a documentary of the same name. In her ad, Clinton says children in those crumbling schools are "invisible to this president," referring to Bush.
