I think she's sabotaging McCain. If you know her history of how she uses people then discards them when they are of no further use to her, this could be an indirect example of that. Questioning why McCain conceded MI, bringing up unsubstantiated allegartions, bringing up Rev. Wright when McCain himself said that, he know Obama and he's doesn't believe in what Wright preached.
Any takers on a Palin 2012 run?
