I wouldn't be surprised either, and from a political standpoint a strong case can be made that at this point it's the best of the lousy options available...(Kavanaugh could withdraw maintaining his innocence but saying something like he was doing so to "spare" his family and the country the "divisive distraction")I wouldn't be surprised if option 3 occurs, combined with allegations of character assassination of this "great American"
To have that nationally televised grilling of Ford (I don't know how she would come across, but the fact that she's a college professor suggests that she's no stranger to public speaking or fielding challenging questions) by the GOP male membership of the Senate Judiciary Committee (they have no female members on the panel) this close to the election would be a PR disaster...
I suspect that withdrawing the nomination would be something that McConnell at this point would be happy to embrace, the sooner the better...(Hell, if he could get it done soon enough, he might even try to take a shot at pushing through a new nominee before the election...)
The one who would no doubt have the toughest time accepting that course is Trump, who is always extremely reluctant to ever seem to be "giving in" on anything related to male mistreatment of women...(For obvious reasons)
Trump's "standard" in these sorts of situations is, "Always believe the man so long as he denies it, no matter how serious the accusation, how numerous the accusers, or how strong the evidence"...
Of course he has to adopt that standard, because it's the only one that gets him off the hook...
