Ford has four to corroborate her story.
1. Her husband whom she told 40 years after the fact.
2. A friend she told, 40 years after the fact.
3. A friend she told, 40 years after the fact.
4. A friend she told, 40 years after the fact.
None of them knew her at the time. None of them know Kavanaugh at all. None were there. None have spoken to or know anyone who knew either Ford or Kavanaugh at the time this "incident" supposedly happened.
Does Ford believe it happened? Probably so.
But here's the thing.
There are things I "remember" from my high school days that I've convinced myself that are true. Those things may not have happened exactly as I remember. And there are people with whom I interacted who probably have very different memories of things that happened at that time.
When I was sitting outside Winnie's house for several hours while she cried over her boyfriend and some junk rubbing eventually followed, does she remember that as me taking advantage of her and then she ran ? I don't. I remember it as a sweet opportunity that never materialized because deep down I'm a nice guy and didn't allow it to happen.
When I rebuffed an advance from Penelope (because I didn't find her attractive, she was drunk and I had a girlfriend) and then she told everyone that I choke-fucked her on the hood of her Cutlass does she remember that I actually choke-fucked her or does she remember the truth? I know I didn't do it, but I was there, we were alone and I can give you affidavits from a hundred people she told. Many believed her.
I'm not saying she's lying in the sense that she's fabricating something. I'm saying that over 40 years it's entirely possible she's created her own narrative to assuage her guilt, as an excuse for bad things that have happened in her life, to make herself feel important, to cover for the fact that nobody really wanted her back then or some for other psychologically convenient reason.
