You can't be serious -- actual rape is hard enough to pursue in the courts, at least without semen DNA, bruising or bleeding or other physical injuries.
What she describes is a clumsy, boorish pass -- which even she doesn't claim he pursued after her objection (and does she watch too many old Doris Day movies?).
I would really like to see her demonstrate what she alleges -- easy enough to set up a mock car seat and steering wheel and find a guy Cain's size.
Who said anything about rape?
