With attendance at Missouri’s 13 casinos down almost 9 percent from last year lawmakers are starting to question the extent to which the state can continue to rely on gambling to fund key programs. Missouri relies on two sources of casino revenues. A portion of a per-patron fee is used to pay for the operations of the Missouri Veterans Commission and a state tax on casino revenues helps fund public schools. State officials are citing this winter’s cold weather among the causes for the revenue decline. In response the House has approved an additional $22 million for public schools and lawmakers are considering a temporary funding boost to help the Veterans’ Commission.
