Not when you look at the voting patterns of Catholics.
And aside from what individual Catholics have admitted to me themselves with their own mouths and told poll takers, it's clear that Catholics vote more liberal as the most heavily Catholic areas traditionally vote in the most liberal politicians.
There's no legitimate way to blame shift that away from Catholics.
The 1973 SCOTUS consisted of 8 Protestants and 1 Catholic and we all know how they changed the culture.
Agreed that the Protestants on the SCOTUS at the time may have been nominal. But I would also argue that faithful Catholics are not the ones voting for the likes of Obama.
