New York state may have been the biggest Kentucky Derby loser of them all yesterday.

The shutdown of Off Tracking Betting parlors and stalled plans to allow betting machines in city bars cost the state $5 million in revenue from lost wagers yesterday — and much more annually.

Manhattan Assemblyman Micah Kellner contends the state could rake in as much as $165 million a year in funds if betting machines were permitted in bars.

The Democrat criticized the New York Racing, Wagering & Gaming Commission for not approving the plan.

“New York has to get back on the horse,” Kellner said. “The New York Racing, Wagering & Gaming Commission, with its stalling, is forcing not only the hardcore handicapper but the casual Kentucky Derby fan to scratch from the race. New York state is losing out on easy money.”

Kellner wants the commission to install betting machines by May 19, the date of the Preakness Stakes.
