Well, that explains why the proportion of women supporting Trump keeps going up

Because no one's out there trying to convince those white women that there's a better choice. Instead, they're being treated as subservient victims who are incapable of standing up to males. So, with that misogynistic attitude toward conservative white women, there is no one to convince them otherwise, their numbers keep growing.

Maybe instead of insulting people who disagree with you, you should treat them as fully-formed humans, put on your big girl pants and try to actually convince them.
