The pro-choice movement is not pro-choice. It stands against the freedom to choose what is right according to the truth of the human person.
I work with a "Catholic for Obama" nut. We went to lunch today and I was explaining to him the ramifications of FOCA. I got his attention when I asked if he wanted to live in a country that tells the Catholic Church if you don't perform abortions in your hospitals you are breaking the law. He said he had never heard of this legislation and asked me to send him a link with some info. I was happy to to do so and as he was leaving today he said he was going to look into this.
I don't know if he'll change his vote but I'll stay on him for the next few weeks.
