Interesting you mention Palin. Some notable similarities. Both are attractive women, happily married with loving families as well as strong personalities in their own right.
IOW, everything the women of the hateful Left will never be.
There is something to be said of the strong conservative woman, who is determined to defend her family like a grizzly bear, who is beautiful, who is smarter than most women, who has 3 or more children, happily married and living a life that is pleasing to God.
Liberals (especially women) despise women like this with the strength of a thousand hell’s. Like you said, they can never be like them - so they’ll do whatever they can to destroy these women of conservative virtue.
Cinderella’s step-sisters come to mind.
