My father has a piece up at the Oxford University Press blog arguing for the confirmation of Sonia Sotomayor. He was earlier in favor of the confirmation of Samuel Alito. He argues that the most important condition is once again satisfied: Sotomayor is a qualified legal professional.
I'm not sure I agree with his argument. Frankly. there seem to be many qualified candidates who have a great deal of experience. I personally am also deeply concerned about Sotomayor's attitude towards both free speech and civil liberties issues ( Doninger v. Niehoff being the most serious example). I worry that with her on the Court many close decisions that would otherwise support civil liberties will otherwise go in the other direction.
In any event, the piece is worth reading and raises a number of interesting points. Go read it.
