Did Brett Kavanaugh just corroborated things Blase-Ford could not have known years ago or even months ago?

1. That Kavanaugh was drunk since Kavanaugh admitted he drank beer and liked beer when he was a teenager
2. That Kavanaugh was at a party with girls on weekends, since he admitted that he was partying on weekends with girls.

Yes

He seems to like hanging around with girls.

Brittford is basically digging his own grave.
