It was quite plausible, if the assault part of her story actually happened, and I have yet to hear Mr. Garrett deny any of it; however, he is on Kavanaugh's character witness list.

It seems highly unlikely that a resident son or daughter wasn't in the house. At this point, it seems even more unlikely that any of this happened at all.
I see a Saturday Night Live skit coming based upon Cory Booker’s “I am Spartacus “ moment.
Where a dozen guys all come out, each saying “I am Ford’s Kavanaugh.”
