DETROIT – A U.S. district court judge has ordered the United States Postal Service (USPS) to speed up its delivery of ballots in Detroit in order to be counted in the presidential election. Delivery of ballots in the USPS' Detroit district has dipped as low as 57% over the past week, Washington state Attorney General Bob Ferguson’s office said Saturday. In fact, the USPS’ Detroit district is considered to have the slowest mail delivery in the nation, according to data released by the USPS. The data shows that mail delivery in the Detroit region was about 15% slower than the national average during the first week of October. The national average mail delivery time has also dropped from 91% of on-time delivery to 86% in October.
