Of course you are aware that the Church has formally condemned the notion of separation of Church and state. The State's primary duty is to act for the common good of the citizenry. The highest "good" is the salvation of souls. Since the ordinary means of salvation are not available to non Catholics, it is a fool's errand to believe that the State can function with out the Church's guidance. As for the Obama religious scorecard, anyone who so rabidly supports infanticide and homosexuality must be given an "F".
