Personally, I thought the case for Kavanaugh having lied under oath about peripheral matters was compelling, regardless of what one thought of the Ford accusations. The one witness that might have been able to confirm whether the event in question happened was not contacted by the FBI. Apparently, this was because of limitations on the scope of the investigation placed on the FBI by the Senate committee. Their was sufficient evidence presented, however, to leave no reasonable doubt that, as a student, Kavanaugh made a regular habit of getting drunk and assaulting young women. Even after the hearing ended, former class mates continued to come forward with tales of his misadventures, all at least consistent with Fords Testimony.
It's obvious Trump did not nominate Kavanaugh because of brilliance on the Bench -- The ABA had down graded him. Dick Durbin once called him the Forrest Gump of Republican Politics. Review of his legal career would suggest he is at least the equal of that when it comes to legal argument. Kavanaugh once authored an obscure article in the Minnesota Law Review in which he argued that a President is "too busy" to be indicted. That may have been what convinced our Jackass President that Mr. Brett Kavanaugh was his man.
