Many states across the country are struggling with billions of dollars in budget gaps and several of them are considering expanding some form of gambling to generate much needed revenue. Lawmakers in Massachusetts today are expected to begin debating a bill to license two resort-style casinos in the state and to introduce slot machines at the state's racetracks. Proponents of the plan say expanded gambling in Massachusetts could create as many as 15,000 jobs and reduce the state's buget deficit.
