They are Catholic. We've been told once a Catholic always Catholic.
This is not a new voting pattern for the Catholic either.
Since 1952 Catholics have voted in the majority for the dimocrat in all but three presidential elections.
I don't disagree with any of the statistics cited here, but they are very misleading because they involve polls of self-identified participants instead of using an objective barometer. If you filter out of the poll anyone who doesn't engage in a modicum of Catholic practice (only include those who attend Mass weekly, for example), the numbers change dramatically.
This poll doesn't show that American Catholics are overwhelmingly Democratic and support outrageous liberal causes. It shows that most American Catholics aren't even Catholic.
