Minnesota’s attempt to use electronic gambling in bars as a revenue source for a new Vikings stadium has proven to be a bust. Governor Dayton says that multiple mistakes caused the first year to be rocky and produce far less money than expected. Dayton says in hindsight revenue and gambling officials were “terribly wrong” with predictions but he doesn’t believe they acted in bad faith. Minnesota has now shifted to back-up funding sources for its share of the $975-million stadium. When the stadium bill was approved, there were estimates that 2,500 bars would install more than 15,000 e-pulltab games. The latest count has about 300 bars and about 1,300 games.
