Ford says she didn't talk about it until therapy in 2012. If Judge actually participated and then bragged about it so freely that it became common knowledge at another school, then it seems likely that not only would other corroborative witnesses exist, but also that an authority figure of some sort would have gotten wind of it and followed up at the time. An investigation might potentially answer some questions, but the partisan, poo-flinging debate over an FBI investigation would probably rival the standoff over the shape of the table at the Paris Peace Accords for sheer futility. Even NPR seems to be throwing in the towel on an investigation, stating that the "short answer" to whether SJC can enlist the FBI to investigate the claim is "no". Cokie Roberts, hardly a Fox shill, has called for Ford to testify regardless of FBI involvement, and Dems in close re-election fights are wavering on that demand as well. All of that comes with the caveat that as with any issue where Trump is involved, common sense and precedent are not in play.
