The doddering old fool, McCain, sent an unprepared Palin on national issues in front of ABC & NBC news anchors itching to make her look bad! No wonder a freshman senator with no experience beat him out.
McCain was literally recruited by the MSM to lose. For years, they built him up, writing puff pieces on him. Why? Because they knew he was flawed, volatile and thus easy to destroy/discredit on command. It was so obvious it hurt.
