New Jersey could have made $300 million on the sale of the two racetracks in the state. A new report by the Star-Ledger said the state was offered the large amount six years ago when the tracks were turning a profit, but the state said no. Christie said on Wednesday it was one of the big mistakes the state has made in recent years. Christie has proposed closing or selling off the Meadowlands Racetrack. Monmouth Park has seen some positive financial numbers this year, as opposed to recent years.
