Kansas City smoking ban

Kansas City barely passed a smoking ban Tuesday that cynically included cigar stores and small bars but exempted the casino gaming floor. Why were the rich and powerful casinos excluded from the public vote? This just looks like divide and conquer to me. Why weren't Kansas City casinos smart enough to see this? When such a law was proposed in St. Louis, not only conservative Christian groups, but even casinos here rejected the exemption and rallied to the cause of mom and pop businesses. Thus we have no ban.
