(No, not that. Get your mind out of the gutter.)
One striking thing about Kavanaugh's confirmation hearings is that at no point was there serious consideration of substituting another reliable conservative. Why? I think it is because Kavanaugh has a handle – something that can be used to flatter or pressure him into ruling in particular ways. We have a hint of it in the reports of his finances – is he perhaps a compulsive spender? Or still a harasser, possibly someone who has committed rapes more recently than in college? There are also hints of that: reportedly he selected clerks based on appearance.
Whatever the reason, I think Justice Kavanaugh is a man who can be controlled by someone, and who is going to be controlled by that someone.
