The picture of Michele Bachmann on the cover of Newsweek was “absolutely” sexist, the former GOP nominee for the 2010 Delaware Senate seat told me. Christine O’Donnell said she speaks from experience when she says women candidates -mainly Republican women – are unfairly treated. “Female candidates get treated differently than male candidates and especially conservative female candidates. And so that’s the double whammy,” she told me. “And there’s all kinds of theories as to why, but I think it’s very clear if you look at the treatment of Sarah Palin, Michele Bachmann, my race.” “The only other person I think who experienced some of it was Hillary Clinton…But certainly I would say not to the level that the conservative women have,” she said on “GMA.” The Tea Party favorite is out with a new book today called “Troublemaker” – where she recounts her childhood and path to an unexpected victory in the Republican Senate primary. A victory that might not have been had a gig with “The View” come through. O’Donnell writes that she interviewed with ABC’s Barbara Walters and told me she “came within days” of being a co-host. “When that opportunity presented itself I prayed about it, is this the right thing to do, and then they called and said ‘We’re going in another direction,” she told me. They chose Lisa Ling. O’Donnell lost in November to Democrat Chris Coons but is still one of the most talked about people in the 2010 races. Part of that attention came from the unforgettable “I’m not a witch” ad – and ad that O’Donnell said today she “hated,” as she first admitted to Jon Karl last October. “We won the primary and everyone said ‘Trust the experts’ and we were trying to win over the NRSC because they were not getting involved,” she said. The lesson in all of this? “If you’ve gotten this far trust your gut, trust your instincts,” she said. Watch my interview here: –George Stephanopoulos or become a fan on Facebook.
