One other point on this question.

For those who don't think Sarah will run in 2012.    You may be right. In fact I hope you are.

But it depends entirely on her ambition.

She is inexperienced, has only been on the national scene a little while.   Where have we seen this before?   Try very recently--e.g. President Obama.

He was admonished to wait, to get more experience, and a better track record.

But he knew he had to seize the moment when it was here--since you can never assume you will ever have a better opportunity. . And he recognized that the 2008 election was his moment.

I'm sure Sarah is getting counsel to wait. But she also knows you need to strike while the iron is hot.

So the question becomes: does she want the job or not?

And all the signs so far point to preparation for a run by her--in 2012.
