Undervotes: This indicates that a voter chose less than the specified number of candidates for a contest. For example, if the contest on a ballot indicated "Vote for One", the voter chose none of candidates. Another example, if the voter was eligible to vote in two contests on a ballot (two seats up for election on a school board), the voter chose to vote in only one of the contests. If the voter did not select any candidate for all contests on the ballot, itâ€™s called a Blank Ballot.
Overvotes: This indicates that a voter chose more than the specified number of candidates for a contest on the ballot. For example, if the contest on a ballot indicated â€œVote for Oneâ€, the voter voted for more than one candidate. This may occur only in absentee ballots, as voting machines in polling places will not allow a voter to vote a ballot with an overvote. NOTE: Any overvotes on a ballot are not counted.
