It would never work. Since the founding of this country Catholics were viewed by some nonCatholics as puppets of the Pope, more loyal to the Vatican than to the US. In some states Catholics were not even allowed to own property. That was one of the reasons the Knights of Columbus came into existence. We have come a long way.
What we do need though, are people who can set aside their conservative and liberal ideologies and nad read church teaching as it stands. I think the Bishops try to do this and then catch criticism from both conservatives and liberals when they do not happen to agree with them. That is why I take their views and statements very seriously whether I agree or not.
