Hey, Joe! The Pope's on line 1!
I found the Cardinal who wrote about denying communion to policitians that support abortion:
On the question of Communion for Catholic politicians, Cardinal Ratzinger outlined a process of pastoral guidance and correction for politicians who consistently promote legal abortion and euthanasia. That process could extend to a warning against taking Communion, and in the case of "obstinate persistence" by the politician, the minister "must refuse to distribute" Communion, he said.

Now I know this only a Cardinal, it's not like he's the Pope or anything...
Right Joe?
