Vance is on record stating women in abusive relationships should stay in the relationship. He opposes no fault divorce because he thinks it makes women too powerful. He opposes abortion in all cases of rape or incest. He wants to give extra voting power to parents with children, because childless people, especially women, "have no stake in the future". He is a rabid misogynist.
This VP selection will solidify even more women against this hideous Republican ticket.
