I'll apologize to you if she doesn't.
Yes, sure, I will admit I am wrong if that happens. No problem at all. And if she goes on to win the nomination, I will vote for her. Heck, I will give her an opportunity to change my opinion about her again. If she runs a great primary campaign and proves to me she could actually beat Hussein, I might even throw my support behind her and be cheering Palin on with you.

I think your bigger problem will be reconciling how you feel about Palin. You've said she is definitely throwing her hat in the ring because she wouldn't have let her supporters believe she is running for so long if she wasn't going to. Therefore if she doesn't run, I assume you will feel completely used and lied to.
