Poll shows county residents favor sales tax hike MILWAUKEE, WI (wuwm) - Milwaukee County Executive Scott Walker and some supervisors disagree over whether to ask residents if they favor a 1% increase in the local sales tax. The revenue would fund the parks, transit and public safety, and lower the property tax. A few days ago, the board agreed not to put a referendum on the spring ballot. WUWM has commissioned a poll through UWM Center for Urban Initiative and Research to learn what residents think of the higher sales tax idea. WUWM's LaToya Dennis has the results.
