Bishop Issues Communion Warning to Voters:

"The Roman Catholic bishop of Colorado Springs has said Catholics should not receive Communion if they vote for politicians who support abortion rights (search), stem-cell research, euthanasia and gay marriage."
...
"'I think it is an outrageous intrusion into what is supposed to be the separation of church and state. It is frightening,' said Michael Merrifield, a Democratic state lawmaker who is not Catholic but represents part of the heavily religious Colorado Springs area. 'It goes against everything that we believe is important to democracy since we founded this country.' "

Quite the contrary. Having a politician complaining about the policies a church establishes and trying to pressure a church into changing its theology to suit the lawmaker's political preferences, is where the "outrageous intrusion" is really occurring.
