How Reliable Is Absentee Voting?

Those who want their votes to count may want to rethink voting by absentee ballot. While absentee voting can be convenient and, for those who are living overseas or who are disabled, necessary; There is evidence that many of these ballots go missing during election times. According to one study, absentee ballots account for about 25% of all election ballots, the number of unaccounted-for absentee and in-person ballots is about the same. The reasons for wayward absentee ballots include delivery problems, errors that make the ballots uncountable and the failure of some voters to return their ballots.
