An "undervote" refers to a situation in an election where a voter does not select a candidate for a particular office on the ballot, even though they have cast a vote for other races or issues. This can occur for various reasons, such as a lack of preference for any of the candidates, confusion about the ballot, or overlooking that specific section of the ballot altogether. Undervotes can be significant in elections, as they may affect the outcome, particularly in close races.
