I disagree. There are putative witnesses to question, classmates of both of them. And please remember, this is not "just" groping. This is someone (according to her story) holding her down, trying to get her clothes off, and covering her mouth. Groping is someone grabbing your butt or your boob. Please know, there is a difference.
The bad faith here is appalling, both on the part of Blasey Ford and the Dems. The accusation was made in June, and Feinstein sat on it during the entire hearings, and never even raised it in her office interviews with Judge K. Ford has framed the matter in exactly the hysterical terms - attempted rape! attempted murder! - necessary to make the event disqualifying if true. Ford says she took a lie detector test in August at her lawyer's office: why would she have done so if, as the Dems contend, she was reluctant to come forward until Feinstein leaked the matter after the hearing was concluded? And now that the Committee has offered her the opportunity to state her case under oath, she is dithering and demanding absurd concessions such as an FBI investigation - and her justification for doing so is identical to the Dems partisan motivation to delay a vote until past the midterm elections.
Ford and the Dems are obviously conspiring to achieve the Dems' partisan ends. This is no quest for justice.
