blank vote
The Spanish term 'voto (en blanco)' translates to 'blank vote' in English.

This usually signifies the voter's indifference, protest, or dissatisfaction towards all of the candidates or the voting system in general. Hence, it is a way of participating in the voting process without supporting any candidate or proposal.
