Scott Horton takes a stab:
In the tough way she approaches prosecutors who appear before her, I see a judge who believes that those who wield executive power have to be held to account for it. That should add to her appeal to civil libertarians, who are generally disappointed with many of Obama’s recent calls on national security issues.
Well, we'll see. After Alito and Roberts, who see the court's role as getting out of the way of all executive claims, we need some kind of balance.
