Implementing a predominantly mail election for the first time can be tricky for election administrators, and sometimes, they screw up. Today we learned that a contractor in Allegheny County, Pennsylvania (home of Pittsburgh), mailed incorrect ballots to almost 29,000 people. Thankfully, the problem was caught and replacement ballots will be sent, but this does appear to be part of a pattern — Franklin County, Ohio (home of Columbus), sent the wrong ballots to almost 50,000 voters last week. So this may be a recurring issue.
