Sarah Palin Vice Presidental canidate, why?

With this recent decision to have Sarah Palin as the vice presidential candidate for the Republican party it has really caused me to take a look at the party and wonder why this decision. I guess I do see the fact that by having a woman as a vice president it will definitely give them plenty of the woman votes. This is obvious by just listening to talk radio. I have been listening the last couple of days and the woman just see this lady as themselves being nominated for the position. They have really made a good decision I believe by picking Sarah Palin. Now the only doubt in my mind is what is her experience?? I understand that she is a governor of Alaska but I really do not want a person in office that is not capable of running the country. Honestly after this race is over I wonder how McCain is going to handle this stress on his older body. She is the one that will take control if he dies while in office. Can we trust her to run our country is the question?
