They always cite these numbers as if they are based on solid evidence (but I don’t remember it being as high as 54% before—I thought 53 or 52%). How did they determine how many Catholics voted for Obama and how many for McCain? How many of those Catholics had been inside a church in the past month? or the past year? I think they include as Catholic everyone who was baptized as one and has not joined another religion.
When you look at Catholics being only 12 % of the voting public — those numbers got skewed — probably with people who said they were Catholic but did not attend church regularly.
Many more people of other denominations voted for Obama than did Catholics.
The Catholic vote consists of people who call themselves members of the Catholic church, and that the Pope counts as Catholics.
They include anyone who self-identifies as Catholic, no matter how long it's been since they darkened the doorstep of a Catholic Church.
