Most New Hampshire absentee ballots are counted without any issues, according to data compiled by the U.S. Election Assistance Commission. However, the same federal voting data shows that about 2% of absentee ballots have been rejected in each of the last four federal elections.
This chart focuses only on domestic civilian absentee ballots cast in general elections, not those returned in primary elections or by UOCAVA (uniformed or overseas civilian) voters.
