Lest you forget: The Postal Service Failed to Update at Least 1.8 Million Addresses
The timing is particularly unfortunate. Starting with North Carolina on September 4, nearly half of all states have now begun sending out ballots and ballot request forms to voters. Many states started long before that to print out mailing addresses for updated voter lists, based at least in part on USPS data. Michael P. McDonald, a political science professor at the University of Florida specializing in voting practices, said it would be difficult to determine how many voters could be affected by the 1.8 million missing change-of-address filings, because election practices and schedules vary from state to state. The error will further complicate election season, McDonald said. I can just see all the litigation after this. It just creates a mess, he said.
