The Associated Press: Del. Senate candidate O'Donnell: 'I'm not a witch' DOVER, Del. In her first campaign ad since winning the GOP primary, Delaware Senate candidate Christine O'Donnell assures voters: "I'm not a witch." O'Donnell's been dealing with questions about witchcraft since a 1999 confession on a late-night talk show surfaced that she had dabbled in it as a teenager. The ad begins running statewide on Tuesday. It opens with O'Donnell looking into the camera and immediately telling voters that she's not a witch. She goes on to say that nobody's perfect and suggests that she's just like everybody else or, in her words: "I'm you." O'Donnell was a little-known candidate until she stunned Rep. Mike Castle to win the Republican nomination last month. The tea party-backed hopeful faces Democrat Chris Coons in November.
