good question

"Father Amaro: Can a person vote for a man running for President, knowing he is for abortion? Will one have to answer to God for this? I know in my heart it's wrong. - Andrew"
Father Amaro answers (scroll most of the way down the page).
personally, I just want to shake these people, but, by the same token that I consider it a necessary penance to watch Top of the Pops now and again to check out the latest atrocities being foisted on the innocent masses by the high priests of popular culture, so I think it useful to check out the current vernacular of god's chosen representatives from time to time. for a priest, this one seems reasonable, plausible, and persuasive (and fairly diplomatic, actually - note that he doesn't actually answer the question). you either buy it or you don't I guess.
