- While less than 1% of the 33.4 million 2016 US election absentee mail-in ballots were rejected, the huge increase in 1st-time mail-in voters could impact the 2020 election outcome.
- The most common reasons for rejection are mail-in ballots received too late and voter signatures not matching signatures on record.
- Many states have deadlines by which mail ballots must be received, not postmarked.
- Voters of color and young voters are the most likely to have their mail-in ballots rejected.
