Here is a good piece on the hypocrisy of it all.
When John Roberts was nominated to be on the high court, Senator Dick Durbin told CNN that he considered it fair game to probe Roberts about his Catholicism. Durbin released a glowing statement yesterday on Sotomayor that never mentioned her religion. When Roberts was questioned by Senator Arlen Specter and Senator Dianne Feinstein, they both asked him whether he agreed with President John F. Kennedy about separation of church and state. Neither even mentioned Sotomayor’s religion in their respective statements yesterday."
