I don't know the circumstances of him leaving the Church. I don't have an objection voting for a non-Catholic - especially when there are no other Catholics in the race. But I do have a problem with a guy who has abandoned the one true faith. He is headed down the wrong road. If he abandons his faith, he can abandon anything. I can't trust him, just like I can't trust a guy who leaves his wife.
I have actually decided not to vote for non-catholics, which is why I had originally decided to abandon my vote for Paroutka, even before I knew that he had abandoned the faith.
I am very near the point of abandoning the "democratic" process altogether. My "vote" goes to the establishment of a Catholic monarchy, and with each passing election that gets more and more clear.
