It is entirely within the realm that Ford is misremembering or intentionally lying, but I can’t think of a single benefit to her in doing so. She will almost certainly suffer personal, and possibly professional repercussions for her testimony even if no one accused her of being a “scorned woman”, and Kavanaugh’s belligerent denial looked less like innocent indigence than aggressive defense by a cornered animal. And regardless of this particular testimony, his previous lies under oath,his nutty conspiracys and losing his temper should have already disqualified him from being confirmed.
EDIT : One more dishonest Kavanaugh tactic that bears mentioning:
They dug up some random Twitter user's insane ramblings and interviewed Kavanaugh about it even though no one else had raised it. Then Kavanaugh used that as proof that the Senate Democrats were conspiring against him. It was a total lie.
With Flake voting yes with the explanation that there just is not enough evidence on either side, it becomes clear that the Republicans only held this hearing so that they could say that they addressed the situation. They don’t want an investigation because they don’t care about the truth; they just wanted to be able to say that they looked into it but there was just not enough evidence. That is why they are ignoring the other allegations. On the one hand, I feel sorry for Ford being used as a pawn by the Republicans like this but on the other hand I am reassured that she got to tell her story and a lot of people believe and support her.
