SuGeAtARC is correct. Her gender is not the issue. People need to point out that there are ethics charges pending against her, she thinks that creationism should be taught in public schools as SCIENCE??!? and she is anti-choice.
Besides, the republicans will make all of the sexist comments you might ever want to hear (assuming you might want to hear that crap).
I was just over at the RealClearPolitics site and they have some of the most vile right wing commenters there. They are making all kind of comments about her being a MILF at the same time they talk about her swaying Hillary voters. And this is from people that think she is a good choice. Talk about incongruous! Maybe they don't realize Hillary voters are not really looking for a MILF! What crap!!!
