I don't think anyone has accused him of having it. They have accused him of being desperate to have it. The stories appear to indicate he was sexually frustrated and couldn't figure how to approach women.
For me, taking account of the women's stories, he sounds like a guy who sometimes reacted badly to booze and this was when his inhibitions were released and his frustration expressed itself.
Republican supporters have clearly decided the women are lying.
I think Dems mostly think he has shown in the hearings that he dissembles. So appealing to his wide-eyed integrity isn't persuasive. Should have been candid in his hearings. Probably had interview practice for his softball Fox News interview. As it was a Fox interview, it was aimed to sure up support from the right and not to persuade anyone else.
