Terry Eastland says that Gonzales should let the President know that he, Gonzales, would not make a good candidate for the Supreme Court. Eastland does a nice job summarizing briefly why this is so.
I suspect that Gonzales has already done this. That is why I think Emilio Garza or Edith Jones fit the bill of being true conservatives but also having either a Hispanic or woman to replace O'Connor. I think that that is something that Bush is concerned with. And so my bet would still go with Garza.
