Attention was understandably focused on Sonia Sotomayor this week, as her confirmation hearings unfolded. But what about Obama's other judicial nominees? The president has so far nominated five judges to federal circuit courts. On average, these nominees are 55 years old, more than a decade older than Sotomayor was when she was nominated to the Second Circuit. (She was 43.) For years, Republicans have been nominating sharp young conservatives to the lower federal courts.
