Wow, so if Christine O'Donnell considers her political life, this is the thing she regrets most?

The Delaware Republican uses [her upcoming memoir, Troublemaker: Let's Do What It Takes to Make America Great Again] to address what she calls "my lowest moment of the 2010 campaign" - a commercial in which she assured voters, "I am not a witch."

She says she never wanted to make the ad - which was prompted by questions about a statement she had made on a late-night talk show years earlier - and was surprised when it showed up on the Internet. She blames an insistent media consultant but also her own inability to put her foot down.

Funny: She says she approved the message at the end of the ad. Oh, well. I guess now we can start taking her seriously.
