Due to the COVID-19 pandemic, mail-in ballots are going to make up a significant chunk of ballots cast this election. One particular concern that some have with the integrity of mail-in voting is the potential for voter fraud from ballots harvested from deceased voters. Recent research from political scientists at Stanford University shows that ballots cast by deceased people are extremely rare. Over the course of 2011-18, the study’s authors found that only 14 of these sorts of ballots have been cast in the state of Washington (where the authors have unique data suitable to test this claim, since the state regularly conducts all-mail elections). This is consistent with other work showing that double-voting is extremely low, and that measures commonly used to address it mistakenly throw out 300 legitimate votes for each double vote detected.
