In Pennsylvania, new data from the U.S. Postal Service show on-time mail delivery plummeted over the last two weeks, even as Pennsylvania saw a record number of ballots cast by mail. In Philadelphia, about 42% of first-class mail took five days or longer to be delivered — compared to just 13% in January. Meanwhile, election officials in Pennsylvania’s Butler County say thousands of mail-in ballots requested by voters appear to have been lost in the mail.

In Minnesota, a federal judge has ordered election officials to set aside mail-in ballots that arrive after November 3 — paving the way for the ballots to be invalidated, even if they were postmarked by Election Day. The ruling overturns an order by Minnesota’s secretary of state requiring ballots received within seven days of the election to be counted.

In Michigan, a state appeals court on Thursday upheld an order allowing the open carry of firearms at polling places. The ruling invalidates an order by Michigan’s attorney general that banned the display of weapons within 100 feet of polling sites.
