Duluth, MN (KDAL) - Minnesota was going to pay its share of the new Vikings Stadium in downtown Minneapolis with revenue from the newly introduced electronic gambling.  Not working!  Gaming revenue from the machines is down.  The estimated revenue from electronic gaming for the friscal year has been cut from 34 - million dollars to less than half - to 16 million dollars.  Minnesota is committed to invest 350 million dollars into the new stadium.  With revenue down, that could be a problem.
