A state lawmaker has introduced a measure that could lead to legalized casino gambling in Nebraska. State Sen. Paul Schumacher of Columbus proposed a constitutional amendment Tuesday to authorize gambling in the state. The measure would not allow casinos within 60 miles of a bordering state, if the border state agrees to share some of its gambling revenue with Nebraska. Gambling revenue would include taxes or licensing fees on games of chance, admission fees, and other taxes. The money would go to the Legislature's cash reserve, state education programs and public transportation needs. One percent of the revenue would go to a compulsive gamblers assistance fund.
