I rooted for Christine to defeat the DemocRAT, dufus brain in 2010, but, that ditzy chick (who just endorsed Romney) was a closet RINO all along. No one sabotaged her campaign but her and her fumb duck campaign manager.
I don’t think that Christine O’Donnell was ever a RINO, or is now. But I think she lost her way by endorsing Mitt Romney. I think her campaign manager, who is Machiavellian in his politics, talked her into it. He hates Newt Gingrich because Newt endorsed Scozzafazza in the NY 23rd special election, where Matt Moran was working for Doug Hoffman. So clipping Newt’s wings while Newt was surging was (I think) the motivation. Also, Mitt Romney was very supportive of Christine O’Donnell in 2010, and Christine has a long memory about things like that. That means a lot to her.
