That number is meaningless.
This number is the ONLY one that matters:
55% McCain, 43% Obama - Weekly mass-attending Catholics
The rest are CINO - "Catholic" in name only.
Unfortunately, CINO applies to far too many Americans who label themselves catholic, including far too many members of the USCCB.
It may matter to you for reasons of pride, but for those of us that are interested in politics and the effect that the Catholic vote has had on our nation, and the fact that we are importing Catholics by the tens of millions, we are interested in the Catholic vote, how the members of that single church vote, and as conservatives, how we can keep it from destroying us and our goals as conservatives.
