Now, if you were an immigrant living in the 1800s I could see having as many babies as possible. Their changes of survival weren't great and you needed to have someone to pass the family farm on to or take care of you when you were in your elderly years (your 40s) and close to death. I can look back through the genealogy book on my father's side and see that many of my ancestors (Irish catholics) had upwards of 10 children. And most of the time 5 or 6 of them survived childhood. It was so very common to have huge families and lose children before their teens.
I don't know. If they want to just keep spewing out children, I'm sure that's fine. They don't seem like bad people at all. I do think that his senate bid is a bit frightening because he doesn't strike me as the type of person who would understand that separation of church and state happens not only on a law-level but an internal level as well. The fact that he's running for government office at all calls into question how much about his own Christianity he understands. But then, he'll be in good company with all the other "Christians" in government.
