Sarah said several times durring the campaign that she and McCain disagreed on a number of things but that she was working on him (not that I think McCain would listen). Perhaps amnesty is one of the points she disagrees with him on. I do know from reading her book and from watching her in interviews, etc. that she loves her country and wants what is best for it so my guess is that she is against amnesty. If Sarah is going to run, she has to say as little as possible right now to keep the media from blowing things out of proportion. They are ruthless where she is concerned. I trust her to do the right thing and she will.
I can assure you that the AZ media and the Hayworth and Simcox campaigns are going to pin her down on this issue, which is the biggest one in the campaign and the reason why McCain has become so hated in AZ among conservative Reps. Her answer could well determine the arc of her political career.
