Pssh, Democratic women are sexy. Kirsten Gillibrand, Democratic Senator from New York, is quite beautiful.
The thing is, women on the left don't appear willing to pander to sexists in order to secure a vote. Senator Boxer wouldn't be caught dead winking at an audience to get a vote because she has something called dignity. I suspect she also has self-respect.
Sarah Palin may be considered attractive for her age (I swear, I don't see it), but she's also borderline retarded and she's a walking, talking gimmick. Her elevation by the right is the biggest slap in the face to women in a generation. She's an idiot, but she's okay to look at, therefore the right accepts her.
