I really didn't see all the sexism from Dems against Hillary that some others appeared to see. I think a lot of people just wanted to vote for Obama during the primaries. The Dem Party was caught. If Hillary won the primaries, we'd be racists. If Obama won them, we'd be sexist.
I do agree with the point of Palin possibly representing the idea of all women being able to claim women's rights and not just a particular group. It's not just conservatives who have a problem with the mainstream women's rights movement.
