Brian Beutler has a post at talkingpointsmemo.com entitled Anatomy Of The (Unsuccessful) Sotomayor Whisper Campaign explaining how:
[A]n unknown number of Second Circuit prosecutors and former clerks banded together and approached The New Republic's legal correspondent Jeffrey Rosen with attacks on the prospective nominee's fitness.
The sources told Rosen, among other things, that Sotomayor lacked the intellectual heft and good manners to serve on the court, and, in an article billed as the first in a series analyses of potential nominees, Rosen went with it.
From there, the attacks went viral.
Susie Madrak at crooksandliars.com adds some more detail in her post Obama Announces SCOTUS Pick: Sonia Sotomayor.
