Palin would be the only one should she get in. Of course if you want to go with the “not any different than any other candidate” I guess any candidate will do.
FWIW, if we want to be critical, it looks like Palin is avoiding throwing her perfect hat in the ring because she has this multi-million dollar a year gig going for her and she's not about to give it up to run for president, even if she is the one most likely to save us. She's also perfectly willing to string along a whole bunch of very good people who have put their time and money and hope into her getting in and saving all of us.
Personally, I don't care what she does and I don't even blame her if she continues to do what she's doing BUT for those who believe she is perfect while all the others are flawed, she may not be so pure after all.
With each passing day, it is less and less likely she is running.
