The Minneapolis Star Tribune reports: "If candidates for mayor of Minneapolis were running in Boston, they would file a report online of their campaign contributions every two weeks for six months before the election. If they were running in Seattle? Once a week. And in a range of other cities with a mayoral election this fall, they would have shared their donor lists at least four months before voters go to the polls. Instead, contenders in the first open-seat race for Minneapolis mayor in 20 years have received contributions for as long as eight months without having to disclose a single detail to the public, and they won’t release their first campaign finance reports until Sept. 3. Campaign-reform advocates and some candidates say that the system is outdated and that it lags the rest of the country, creating “data dumps” that hinder the public from learning the information in a meaningful, timely way."
