The left assaulted Sarah because she represented the wedge issues that fueled the Bush - Rowe victories: God, guns and gays. She was an election winner and had to be destroyed. Obamachev signaled that it was OK to slime her by calling her a pig. We have to admit the campaign against her was successful.
I think McCain made a mistake tapping her with little time to prepare for national exposure. Maybe in 2012, Sarah will be more prepared.
