Baldasaro is among gaming expansion proponents who want to see the Legislature authorize multiple casinos, something the governor has said she opposes.
He said New Hampshire is losing millions of dollars to Massachusetts because keno players can go there to bet, but not in their home state.
Baldasaro’s objection to keno in Massachusetts is that keno is allowed at neighborhood stores.
“I want it to go into bars and restaurants, not seven-day stores,” Baldasaro said earlier this year.
He also would let veterans’ organizations like the American Legion and Veterans of Foreign Wars have keno in their local posts.
The keno study is supported by the Lottery Commission, Hess said in his report to the House.
The bill calls for the study, if approved by the Legislature, to be completed this fall.
