It may have been necessary for Christine O’Donnell to deal with the “witch” deal, and show that Christine is “normal.” Her first ad does that.
But once that ad has been widely seen (I am assuming it now has), she needs to stop reminding people about those aspects, and create a very hard hitting, very on-point message. That means to hammer the difference on the issues between Christine and her opponent. The Democrat cannot win if people have the issues in their mind, and that’s where the fight has to be waged.
