Sen. John Marty, a longtime critic of public subsidies for stadiums in Minnesota, really has a problem with the proposed Minnesota Vikings stadium in Arden Hills.The DFLer from Roseville said the Vikings proposal would hit taxpayers in Ramsey County more than three times as hard as taxpayers were hit in Hennepin County when the Minnesota Twins ballpark was built. Marty's district is in Ramsey County."For every 30 cents Hennepin County taxpayers pay for the Twins ballpark, Ramsey County taxpayers would be paying $1.00 for the Vikings tax – that's three times the tax increase," the legislator said in a statement.The Vikings proposal to build a $1 billion stadium in Ramsey County's Arden Hills has yet to have a public hearing at the State Capitol. Under the plan, the team would contribute at least $407 million, the state would add $300 million and Ramsey County, through a half-percent county wide sales tax increase that would include St. Paul, would raise $350 million.The Twins ballpark, which opened last year, is being largely financed by a .15 percent sales tax increase in Hennepin County, which includes Minneapolis, the state's largest city.Marty said stadium supporters "are trying to hide the size of the taxpayer subsidy by talking only about the state tax increases and virtually ignoring the impact of the local tax increase."
