yeah, cardinal ratzinger, our new pope, wrote this:
Regarding the grave sin of abortion or euthanasia, when a person's formal cooperation becomes manifest (understood, in the case of a Catholic politician, as his consistently campaigning and voting for permissive abortion and euthanasia laws), his Pastor should meet with him, instructing him about the Church’s teaching, informing him that he is not to present himself for Holy Communion until he brings to an end the objective situation of sin, and warning him that he will otherwise be denied the Eucharist.
no body of christ for you!
