The mail-in ballots of more than 150,000 citizens were not processed by the Election Day deadline even though they were in the possession of the USPS on or before election day, the Washington Post reports.
Those ballots may not have received the required November 3rd postmark required for them to be accepted by election boards, meaning those votes were nullified.
At least 12,000 of those votes, which were processed but not delivered on Election Day, were in states that are still undeclared in the presidential race. By state law, some states, like Nevada, where 4,518 ballots arrived after Election Day, as well as North Carolina (2,958) and Pennsylvania (3,439), can process ballots received after November 3rd if they are postmarked by Election Day.
The votes going to Arizona (864 ballots) and Georgia (853 ballots), however, cannot be counted because state law requires the ballots to be in possession of election officials. Those votes, per law, cannot be accepted because of the USPS delay.
