Sooner or later the Catholic faith of Judge Sonia Sotomayor will be raised as an objection to her nomination and appointment to the Supreme Court of the United States.
Judge Sotomayor is a moderate. As a consequence, she is just as likely to be attacked from left as from right. That's probably not what President Obama means by common ground, but one can admire him for finding a woman seemingly so capable of adhering to the law rather than her personal opinion, and for on occasion, even resolving cases contrary to the president's own policy perspectives.
One possible objection to Judge Sotomayor from the left will be her Catholic faith. There are already five Catholics on the court, it will be said. When the court upheld Congress’ limits on the partial-birth abortion ban, there were more than a few grumbles that it's just those Catholics having their way. Completely unfair. Anyone who actually read the opinion knows different.
