In a stroke of media mastery, Bristol Palin harnessed the Palin-family-doting Fox News last night to announce a powerful (and decidedly non-Fox News) message for policy makers: abstinence only is "not realistic." The new teen mom also told Great Van Susteren that she would "love to be an advocate to prevent teen pregnancy." Making this announcement on one of the most watched, and most conservative, news stations in the nation is already a pretty good display of her ability to reach a large swath of Americans (particularly the most difficult to reach on this issue.)
