I may be paraphrasing but I believe he said, "Compromise is the essence of democracy", or something very like that. Putting aside his misrepresentation of our form of government as a democracy, I do wonder why no one followed up and asked him what sort of compromise he would accept when it comes to abortion.
He also stated, when discussing his visit with the Pope, that Francis represented the best of Christianity, Obama's purported Christianity in any case, in that the Pope promotes compassion for the innocent. Just like Obama does for every aborted fetus.
