She wants to be president.
She believes in nothing else. She stands for nothing else. She has no other principles.
She will believe whatever beliefs the voters will vote for. She will stand for whatever stances the voters will vote for. Her principles will be whatever principles the voters will vote for.
The primary is her "listening tour." She said so herself. She is listening so she can find out what she should believe, what she should stand for and what principles she should hold. Once the voters have made that clear she will be able to speak out definitvely and clearly.
But she has a problem. There are too many conflicting beliefs, stances and principles out there. She is going to have to try to come up with a campaign that will embrace all of them and her head will explode.
