Ok, of course I don't want a President who makes major decisions based on emotion.
Fortunately, I disagree with you, and believe she thought this decision through before endorsing McCain.
I don’t think supporting McCain at this point is a major decision of epic proportions to get bent over.
I would relax. She is more then effective fighting Obamanation, and if anything, she will have good effect on McCain and maybe snap him out of some Rinoism.
