I doubt that very much. I think she will endorse Perry if he runs, giving him a powerful boost, as they have been friends and political soulmates since long before anyone ever heard of her in the lower 48. I don;t think she wants to be second fiddle again.
She has her eyes on the top prize, and I think she will get there, but to do so she will need to overcome her (perceived) lack of experience and persistence. I see her as Energy Secretary for Perry, perhaps followed by a term or two in the Senate, and then a successful run at the Presidency .
Sarah is a young woman still, and has a good twenty-five years of political viability left. With careful and diligent service she will be able to overcome her current negatives, and when the time is right she will become our first woman President with relative ease.
I don't believe another run at the Vice Presidency is the way to go, though, and I will never forgive McCain for pulling her up to the big leagues too soon.

Palin will not get the prize if she teams up with the likes of Perry.
