A new analysis has identified that at least 12 states saw an increase in the number of mail-in ballots that arrived after the established state deadlines, rendering them ineligible to be counted in recent House, Senate, and gubernatorial elections. The report highlights a recurring issue where voters, despite attempting to participate by mail, had their ballots excluded from final tallies due to the timing of their arrival.

While the report confirms the volume of uncounted ballots, it does not specify the exact margin of impact on the final election outcomes in those states. The data underscores the logistical challenges associated with mail-in voting systems, particularly in states with strict deadlines that require ballots to be physically received by election officials by the close of polls, rather than merely postmarked by that date. The findings raise questions regarding voter education and the efficiency of postal delivery services during election cycles, as thousands of voters potentially had their intent to vote nullified by transit delays.
