Follow the money. 20 million illegal aliens, about 2/3 from supposedly Catholic countries, at say $2.00 a week in the collection plate, comes to about $13 million a week if only half of them show up in church.
Reverend Ike would like a haul like that too.
It's especially true for young male recent-arrivals who send half their income back to their families in Mexico. They mostly don't come to church; and when they do, they mostly don't put anything in the basket.
