Trump commands anyone who is not a "Christian conservative" to identify themselves

"Raise your hand, Christian conservatives, everybody. Raise your hand if you're not a Christian conservative. I want to see this, right. Oh, there's a couple people, that's all right. I think we'll keep them. Should we keep them in the room? Yes? I think so." - Donald Trump at an Iowa rally today. At the next rally he'll have a box of yellow star buttons to pin on them.
