Duh? The USCCB did buck the EO approach.
They bucked it with words, but clearly did not put Stupak under pain of excommunication to walk away from it.
They kept silent in the pulpits for weeks and months, only to register some lame token opposition as the vote was about to take place.
They secretly met with the Obama Administration to see if they could thread the needle on having their cake and eating it too.
Kind of hard to get a cake through the eye of a needle.
