I think Barnes is also wrong in his description of Souter "drifting left" as well. While some Justices have "grown" over the years, Souter went through a pubescent growth spurt within a year of joining the Supremes.
Does anyone know what Sununu and Rudman had to say for themselves? They vouched for the guy, and yet, soon after being seated, Souter sure didn't waste any time doing a sharp left. Did he have them fooled or did they just plain mislead 41 about how he'd be?
