The thing about Kavanaugh is that it's 100% obvious that thew knew he had some sort of questionable incident(s) involving women in his past. The "he's a girls' basketball coach" is such a conservative way of trying to "deal" with that problem, even though it's actually the creepiest possible way to try to deal.
Knowing doesn't mean they believed it, and certainly didn't mean they cared about it other than as a LIEBERAL obstacle to conservative Nirvana, but they knew.
