The bingo-like lottery game that began this summer in Ohio to help plug the gaping hole in the state budget is off to a slow start. Keno has been hindered by a weak economy and challenges getting it established at 2,000 bars and restaurants, said Mike Dolan, executive director of the Ohio Lottery. Keno started August 4. The game is a central part of Governor Ted Strickland’s plan to insulate the state budget from the economic downturn that has dried up tax revenue.
