One other possibility about Palin in SC....Palin was the earliest and most prominent supporter of Nikki Haley in SC. And we all saw how well Gov. Haley was treated during both the primary and, most baffling, even during the campaign by the good ol’ boys in the SC GOP. Palin might not be the preferred prez candidate of these GOBs.
Sexism is no myth. Male pols are very competitive and they hate the idea of competing with women, especially competitive women. And Palin is that. The rap on Hilary was that she was a “wife,” but she is tougher than Bill is.
