Game Change is not about saying that Palin lost the election for McCain. Democrats think that Obama was a great candidate. The goal is to ensure that Palin is and remains a pariah for the increasingly oikophobic and transnational managerial class. It is about preventing them from voting for Romney.
If it had not been for Palin, McCain would not have gotten one theth the votes he got. Myself and a lot of people I know voted for him after saying that we were not going to vote for him after he picked Palin. If the sob woulf run again on his own, you would see just how popular he actually is outside Arizona.
