First, there is no evidence whatsoever that Roberts “sought to alter” the draft report.
If you read the draft, and the final, the only thing that happened was that a) Alito directly responded to the dissents in detail, and b) Roberts’s concurrence, which I examine at length in Today’s News at www.uncoverdc.com, was extensive. These both take an exceptional amount of time to write. Alito had to look at every case the dissenters cited, and then find his own case law.
So I think Roberts was far too busy on his concurrence to bother trying to change minds, which he knew wasn’t going to happen anyway. If ACB and Kavanaugh, who HAD THEIR LIVES THREATENED and had stalkers outside their homes, weren’t moved by that, they sure weren’t gonna be moved by little Johnny’s petitions.
Do you have a current guess as to who the leaker was or who the leaker worked for?
