WINONA, Minn. – Cash-strapped municipalities deserve a bigger share of the state’s $9 billion revenue surplus, according to Winona Mayor Scott Sherman. This year, Sherman says, the state’s local government assistance has increased only $5.5 million.  In a KWNO interview Sherman said he will continue lobbying through the Coalition of Greater Minnesota Cities and the League of Minnesota Cities for more funding. “We’re not seeing the kind of increase that would be appropriate for the amount of surplus at the state level,” Sherman said.  The mayor estimated state funds for Winona comprise 15% to 20% of city budget. Not enough, he said. Last year the city received $10.2 million, which the mayor said may increase slightly to $10.3 million this year.
