Obviously you don't follow SP much, or know much about her to be arriving at such a conclusion. That's ok, there's still time for you and many others to vote your true conscience.
I and many millions of others just don’t think Sarah Palin plans to run for President. So when it finally becomes apparent around Christmas time that she has still not announced her candidacy what will you do? You will either have to select another candidate or just write Palin’s name in on your ballot which would be a wasted vote.
I’m no longer convinced that Perry is a RINO. I think maybe Palin feels the same way.
