Mail-in voting, which tens of millions of Americans are expected to use this November, is fraught with potential problems. Hundreds of thousands of ballots go uncounted each year because people make mistakes, such as forgetting to sign the form or sending it in too late.
An NPR analysis has found that in the primary elections held so far this year, at least 65,000 absentee or mail-in ballots have been rejected because they arrived past the deadline, often through no fault of the voter.
