McCain asking Sarah to campaign for him is an admission on his part he needed her in 2008 and still needs her now. It’s also another opportunity for Sarah to be in front of future voters. She should be scrutinized by voters - but no more and no less than any other potential candidate.
He DIDN’T need her. He chose her out of spite. Don’t you get it? He intended to lose the election. mxain went into doubleshock when Sarah APPEARED to be bringing him more support than he ever thought possible. THAT is why he tried so hard to shut her down and shut her off.
It scared him to death that she might actually make it possible for him to win.
