Politico had an article giving 6 reasons that McCain picked Palin.
6 things the Palin pick says about McCain - Jim VandeHei and John F. Harris - Politico.com I kind of agree with the article. McCain had only met her one time before. As of the 15th., she stated that she had not been vetted. I don't think that she has been thoroughly vetted to this date. While, I'm sure that she appeals to the far, far, right, she seems to be a very odd choice.
I think McCain just gave the election to Obama.
