In November, Maryland voters will decide on Gov. Martin O'Malley's proposal to legalize slot machines in the state. The current debate on the issue is completely different from the one that took place under Republican Gov. Robert Ehrlich, who lost his bid for re-election in 2006. Mr. Ehrlich regarded slots as a means to save the state's horse-racing industry, and he preferred raising revenue from legalized gambling to increasing taxes. But Mr. O'Malley, Senate President Mike Miller and House Speaker Michael Busch have different agendas in mind with the slots referendum, which include massively increasing the size of government, and possibly the creation of some form of a state-run health care system in Maryland.
