A judge has kept in place guidance from Iowa’s secretary of state that county elections commissioners can only set up absentee ballot drop boxes at or outside their offices.Judge William Kelly rejected a request from a Latino civil rights organization and a group aligned with Democrats to block Secretary of State Paul Pate’s guidance and allow for drop boxes in locations such as grocery stores.The ruling, coming nearly three weeks after Kelly heard arguments in the case, isn’t expected to have an impact because it comes so close to Election Day.
