Brave New Films has produced a powerful short film about Brett Kavanaugh's lying about his heavy drinking in high school and college:
Keep in mind that there's a very good reason he is lying so blatantly. If he were to admit that he drank to excess and blacked out at times, it would lend credibility to Ford's testimony. Why? Because it would mean that he and his admitted black-out drunk pal Mark Judge could very well have committed the act they are accused of --- they were sloppy, rowdy drunks who showed contempt for the girls they socialized with (he's alleged to have waved his wang in his Yale classmate's face) and may even not remember doing it.
So he lied. Because to tell the truth would have been to admit that it was possible. High school and college frat boys may drink a lot of beer. But when they drink this much, this excessively, and talk about girls the way they talked in their yearbook pages, it lends credibility to the accusations. And he knows that. All those drunken assholes he hung out with in school know it. That's why he can't even admit that he was such an excessive drinker that he commonly drank until he vomited.
