Elizabeth Brown on Communion

Elizabeth Brown wrote the follwing to me in response to my post on access to the Eucharist: On the Catholic politicians, Communion and voting postings that you and
others have made to MOJ, I am surprised that no one has mentioned a couple
of issues:

1.  Giuliani and Communion:  As a divorced Catholic who is remarried, he is
barred from receiving Communion on the grounds that he is committing
adultery.  So the "threat" of withholding Communion because of his views on
abortion is somewhat of a paper tiger.

2.  Politicians and Torture:  The US Government under Bush has and continues
to engage in torture.  Some of the Republican politicians, like Romney and
Giuliani, are making even tougher security measures hallmarks of their
campaigns.  Romney would "double" Guantanuamo.  Since torture like abortion
is a non-negotiable prohibition, why are the Catholic bishops and others not
making the case that to support a politician precisely because he or she
will support the use of torture (allegedly to protect the US, although
torture NEVER has been proven to provide any reliable, actionable
intelligence) would place the Catholic outside of Communion with the Church
and they should not present themselves to receive the Eucharist.  I know
that some polls indicate that a significant number of American Catholics
support the use of torture by our government.  So if using Presidential
elections as a teaching moment on abortion is appropriate (as some clearly
think it is), why are the same people not using them as teaching moments on
torture as well?
