Have a baby, save the world

Whew! I suddenly feel a lot better about the future of the world. I read this article about modern demographics and I can breathe a lot easier now. In a nutshell, liberals aren't having families or are having single child families, ala Bill and Hillary Clinton (Chelsea), conservatives are having relatively larger families (Mormons & Catholics). The net result of this is that liberals are de-procreating themselves out of existence. Don't get it? Read the article. It seems so simple but it also seems to make a lot of sense. What do you think?
