One of the major lines of defense deployed by the advocates of Brett Kavanaugh is the idea that this is a case of mistaken identity. In her testimony before the Senate, Christine Blasey Ford rejected this as forthrightly as possible.
Senator Dianne Feinstein asked Ford how she was “so sure” it was Brett Kavanaugh who covered her mouth in the alleged attack. “The same way I’m sure I’m talking to you now,” Ford responded. “Just basic memory functions and also just the level of norepinephrine and the epinephrine in the brain that as you know encodes that neurotransmitter that codes memories into the hippocampus and so the trauma-related experience is locked there whereas other details kind of drift.”
Refining the question, Feinstein asked if “this could not be a case of mistaken identity?” Ford responded, “absolutely not.”
