From this article, someone from the McCain camp says about the SNL skit starring Tina Fey as Palin and Amy Poehler as Clinton (if you haven't seen it, you're way behind - just google it and watch it already):
“The portrait was very dismissive of the substance of Sarah Palin, and so in that sense, they were defining Hillary Clinton as very substantive, and Sarah Palin as totally superficial,” McCain advisor Carly Fiorina told MSNBC’s Andrea Mitchell on Monday. “I think that continues the line of argument that is disrespectful in the extreme, and yes I would say sexist.”
Hoo-kay. Implying that Hillary Clinton is substantive while Sarah Palin isn't is sexist. That's a new one.
