CONCORD, N.H. – Gov. John Lynch said Friday he would veto a bill to legalize video slots in New Hampshire if it reaches his desk.

The House will vote Wednesday on a Senate bill to allow the gambling operations at six sites in New Hampshire, including two on the Massachusetts border.

Lynch said he would veto both the Senate bill and one proposed in the House that scales back the number of sites to five. The governor said the House version was not an improvement.

But Lynch did not slam the door shut entirely on expanded gambling in New Hampshire. He said he wants to review a report by a gambling commission he appointed last year to study the issue and analyze possible gambling models for the state.

“Other governors tell me that it is absolutely critical to have in place a proper and comprehensive regulatory and legal framework prior to going forward with a discussion of what the models should be,” Lynch said.

The gambling commission report is due by early May.

If the House kills the Senate bill, gambling supporters could revive the measure during negotiations to close a projected $220 million budget shortfall by July 2011. But Lynch said Friday that lawmakers should not look to gambling revenue to close the gap. Lynch said his plan to address the shortfall, which does not include gambling, should be the starting point for budget discussions.

The Senate bill would allow 17,000 video slot machines at three racetracks, a golf course resort and two undesignated sites in northern New Hampshire.

The House proposal would cut the number of slot machines to 10,000 and eliminate one North Country site. It would require applicants to compete before a tribunal to secure a site each in central and northern New Hampshire.
