CUNNINGHAM: The Minnesota Vikings returned to the state Capitol today (TUESDAY) to continue their campaign for a new stadium. The Vikings are seeking a $500 million stadium to be shared with the University of Minnesota Gophers. But the Metropolitan Sports Facilities Commission is advancing a plan to renovate the Metrodome. The commission -- which owns and operates the facility -- told a tripartisan stadium task force that renovation would be cheaper -- and would solve many of the Vikings' problems in the current 'Dome. Minnesota Public Radio's Michael Khoo joins us now. Michael, what does the commission's plan entail? KHOO: Greta, the commission members say they'd like to turn the Metrodome into a football-only stadium. That would mean building a new ballpark for the Twins, and remodeling the facility to fit the needs of the Vikings and the University of Minnesota Gophers. A commission study estimates the cost of renovation at roughly $250 million dollars, or about half the cost of the new stadium the Vikings favor. The team has so far dismissed the renovation plan, but commissioner Richard Jefferson, **a former state legislator,** says it's important to explore all options.
