PRRI Catholic Support for Same-sex Marriage by Attendance-thumb-500x350-423

It's worth pointing out, for the record, that even if you measure those American Catholics who attend church weekly, the numbers are pretty decisive: 64 percent favor either civil marriage or civil unions for gay couples. Only 31 percent take the Vatican line. K-Lo thinks the shift from 74 percent overall approval and 64 percent approval among the weekly mass-goers is "dramatic." I'd say: not so much. The Vatican has lost this argument in the developed world.
