Presumably, two daggers means more bulk sales.
The Atlantic contacted the publicity department of St. Martin's Press, which published Romney's book, seeking information on bulk orders by individuals or groups; St. Martin's has yet to respond with any detailed sales info, and I'll update this post if it does.
Conservative groups, it would seem, might be interested in obtaining copies.
