Go Sarah Go.
I would be shocked if that happened. I believe she is sincere in her love of Alaska and her desire to protect her family. And there is nowhere she can protect them better than in Wasilla, surrounded by relatives and friends. If she does reenter national politics down the road she will need that refuge to return to.
And it must be miserable for New York / Washington press to have to travel there and cover her. That alone makes staying worth it.
