Nothing Brett Kavanaugh said at his hearing would have changed anyone’s vote. If I am at a job interview in the future, this is what I would say:
Asking questions about what I did or did not do 30 plus years ago is irrelevant to the decision you are trying to make. You are not trying to decide if I should receive a life-time good conduct medal. None of us are the same person we were 30 years ago. What is important today is can I / will I do the job at or above the expected performance level.
