Kentucky voters should have a chance to decide whether to let Indiana keep trucking Kentucky money across the Ohio River to casinos like Horseshoe in Harrison County. Here at Louisville, despite spring flooding and the closure of the Sherman Minton Bridge, Horseshoe Casino still took in revenues of $252 million for 2011, and the great majority of the license plates in the parking lot belong to Kentucky drivers. During Derby week or any major convention, I watch the shuttles stop at our hotels and take our visitors to the boats. Louisville's signature institution, Churchill Downs, just wants a level playing field with the Indiana casinos. Gaming presents challenges, like gambling addiction, and it's not a reliable long-term revenue source. However, Kentucky voters should have an opportunity to judge the potential benefits and burdens and decide for themselves. If gaming is expanded, casino sites should be limited, and a stream of revenue needed to help the horse industry should be insured.
