The shouters in the crowd have been outed as Obama and pro-abortion supporters. The degree to which the left has attacked Palin is beyond the pale. Obviously, they fear her. Why else would they attack someone out of office who is only promoting a book? It shows you how desperate they are. They know their policies are failing and their lies are being exposed.
With the president polling south of 50% approval, they have every chance of losing power in a big way next year and they know it. Sarah Palin is a potential leader of the opposition and they want to discredit her as much as possible. It seems, however, as usual, they are over playing their hand.
