You're either skipping or ignoring the part about how the A.G. has to run the department of 150 people and he said he didn't know how to do it and would probably get someone else.
As for having a J.D.... every lawyer has a J.D.! Even Alberto Gonzales. That doesn't mean that Joe Ambulance Chaser is equally qualified to be the Attorney General.
Seriously, I thought that even conservatives were on the same page as the rest of us about cronyism after what happened with Harriet Miers and Alberto Gonzales (each of whom had a J.D.) Do we need to go through the same arguments again, learn again the hard way, because this time George W. Bush is wearing a skirt and hunts moose?
