The public — that is, society as a whole — was revealed to be deeply divided, not just about the nominee himself and his suitability, but about wider questions as well.
On the one hand, there were those who applauded the courage of the woman who gave evidence about an alleged assault on her by the nominee and were satisfied that she should be believed. Her courage and credibility became an article of faith for large numbers who saw the episode as further evidence of the treatment suffered by many women at the hands of sexual predators.
On the other hand, were similarly large numbers who professed to see the allegations as politically motivated — "she was paid by the Democrats to say those things", according to some Trump supporters — and who agreed with the President that men were being unfairly targeted and themselves needed protection.
In the end, then, the controversy may have produced a victory for the nominee and for the President, who now has a Supreme Court (as his supporters wanted) with a majority in favour of conservative social attitudes - on abortion, gay marriage and women's rights.
Brett Kavanaugh's appointment was, incidentally, the second appointment, following the appointment of Judge Clarence Thomas, of a judge who holds such views but who was also, as a nominee, accused of similar sexual behaviour.
Kavanaugh's appointment was, in other words, achieved at the cost of laying bare and exacerbating the deep and visceral divisions that rack American society. A President and a process that should have tried to heal those divisions succeeded in doing the opposite.
Yes, they do things differently there. Despite our admiration for so much that is American, we can be grateful that, at least in this respect, we do not model ourselves on everything they do.
The Kavanaugh episode should at least teach us that highly politicised processes can be deeply damaging and that short-term political victories can sometimes be achieved at a cost that is too high to pay.
