Supreme speculations

Now that the shouting over Roberts is simmering down, folks are turning to speculations over the next nominee. In addition to the candidates discussed the first time around (such as Alberto Gonzales or Priscilla Owen; see here) there is a lot of curiosity about whether Bush could dig up another "dark horse" like Roberts, with no paper trail to be held accountable for but with powerful conservative credentials. The most intriguing such speculation, to me, is laid out by Will Bunch: Harriet Miers. Die-hard Bush loyalist? check. Little or no judicial history? check. Has some political owage? check! (Bunch thinks she "knows where the bodies are buried" on Bush's National Guard shame.) Other promising parallels? check: Cheney was asked to help pick a Vice Presidential running mate and eventually suggested himself; Miers was in charge of the short-list for Supreme Court, and after Roberts . . .
