None of the above in the context of "Abstention"

Abstention is a term in election procedure for when a participant in a vote either does not go to vote (on election day) or, in parliamentary procedure, is present during the vote but does not cast a ballot. Abstention must be contrasted with "blank vote", in which a voter casts a ballot willfully made invalid by marking it wrongly or by not marking anything at all. A "blank voter" has voted, although their vote may be considered a spoilt vote, depending on each legislation, while an abstaining voter has not voted. Both forms (abstention and blank vote) may or may not, depending on the circumstances, be considered to be a protest vote (also known as a "blank vote"). Abstention is related to political apathy and low voter turnout.

An abstention may be used to indicate the voting individual's ambivalence about the measure, or mild disapproval that does not rise to the level of active opposition. Abstention can also be used when someone has a certain position about an issue, but since the popular sentiment supports the opposite, it might not be politically expedient to vote according to their conscience. A person may also abstain when they do not feel adequately informed about the issue at hand, or have not participated in relevant discussion. In parliamentary procedure, a member may be required to abstain in the case of a real or perceived conflict of interest.

A protest vote (also called a blank, null, spoiled, or "none of the above" vote) is a vote cast in an election to demonstrate dissatisfaction with the choice of candidates or the current political system. Protest voting takes a variety of forms and reflects numerous voter motivations, including political apathy. Where voting is compulsory, casting a blank vote is available for those who do not wish to choose a candidate, or to protest. Unlike abstention elsewhere, blank votes are counted.

Along with abstention, or not voting, protest voting is a sign of unhappiness with available options. If protest vote takes the form of a blank vote, it may or may not be tallied into final results. Protest votes may be considered spoiled or, depending on the electoral system, counted as "none of the above" votes.
