Not True.
Back when I was in HS, long before any of this supposedly happened there were a few girls who went to "rape parties" every weekend. They enjoyed it.
The were called "sluts" and they were real. And, no it wasn't rape -- it was consensual. Now over the intervening decades their attitudes may have changed and in their own minds it became "rape".
Whether Kavanaugh ever went to a party like that is an open question
Nobody corroborates her, and she has a history of lying. Avenatti went looking for people like her with cash in hand. She never surfaces unless he goes looking for her.
That’s why the question of her being more believable with another attorney is a bogus question.
