Sarah Palin is driving reporters crazy because she is not allowing any questions and she isn't giving them any information about her bus tour across the country.
Note to reporters: Stop following her.
Right now she's just a Fox employee, not a candidate. If she becomes a candidate, she will have to answer questions, and if she's still too gutless to answer, the American public gives you permission to absolutely hammer her. You can't run for office without answering questions from the press. It's the reason we have the press. Otherwise an election is a pointless PR exercise.
But until she announces, she's under contract not to answer your questions. You're just giving her free publicity for no reason at all. Pictures without substance. It's exactly what she wants.
