A bill that would create a regulatory structure for sports gambling in New York appears to be on the ropes, as support remains insufficient in the Democratic conference in the Assembly to bring the measure to a vote.

“We had a pretty lengthy conference yesterday and members raised significant issues,” Assembly Speaker Carl Heastie said on Thursday. “So, I would say at this point there isn’t enough support within the Democratic conference to go forward on sports gambling.”

A concerted push began last month on the bill after the Supreme Court struck down a federal ban on sports gambling, leaving the issue up to the states.

An existing law allows the state Gaming Commission to structure regulations now for allowing sports books in commercial casinos. Lawmakers would act on additional issues, shaping the regulations for major sports leagues to crack down on illegal activity and allow betters to make wagers on mobile devices.

Lawmakers, however, are running out of time to finalize an agreement. The legislative session ends on Wednesday.

“I don’t want to never to say never in this life, but I don’t know if a week is enough,” Heastie said. “Sometimes that can be a lifetime. But the broad spectrum of concerns members raised, I don’t know if that can be resolved.”

In the Senate, Racing And Wagering Committee Chairman John Bonacic said he’s tried to accommodate concerns raised by the Assembly.

“If (the Assembly) comes up short, then in my opinion the sports betting bill will be dead,” he said. “Everyday we get a new count. It’s a day by day, but we’re running out of time.”

Bonacic’s Assembly counterpart, Democratic lawmaker Gary Pretlow, said a range issues were raised in the closed-door conference, including the impact on state agreements with tribal casinos and questions of constitutionality.

“The real problem is time. Today is Thursday. We’re done in four business days, but anything could happen,” he said. “This is the New York state Legislature.”
