Levada urges discussion of politicians-and-communion issue

"The Vatican's top doctrinal watchdog, American Archbishop William Levada, has urged a meeting of the world's bishops to discuss whether Catholic politicians who support abortion rights should receive Communion, saying the issue had divided many of the faithful in the United States."  (link). (By the way, is anyone else really tired of hearing the head of the CDF referred to as a "doctrinal watchdog"?  I just googled the term, and got about 900 hits).
