Advert for Republican Christine O'Donnell: 'I'm not a witch'

The Republican candidate to represent Delaware in the Senate, Christine O'Donnell, has produced a simple advert in which she tells voters in a direct appeal, 'I am not a witch ... I am you'.

Her campaign was knocked off balance by revelations that she dabbled with witchcraft in college.

Ms O'Donnell's comments about witchcraft were made during a 1999 taping of comedian Bill Maher's Politically Incorrect show.

"I dabbled into witchcraft, I never joined a coven," she said on the show, comments which were recycled in the media.
