Yahoo News reports three conservative Catholic Supreme Court justices failed to take advantage of their reserved seats to hear the Pope speak to Congress. I believe you can generalize from this boycott the reactions of conservative Catholics to the liberal message Francis has delivered.
The three - Scalia, Alito, and Thomas - aren't buying the message, or the man. Expect many conservative Roman Catholics to follow suit. Peronist liberation theology is anathema to conservatives.
It appears Rome has elected its own Barack Obama. A bureaucracy that has persisted 2000 years probably has sufficient inertia to survive the challenge Francis poses.
