A protest vote (also known as a blank vote or white vote) is a vote cast in an election to demonstrate the voter's dissatisfaction with the choice of candidates or refusal of the current political system. In this latter case, protest vote may take the form of a valid vote, but instead of voting for the mainstream candidates, it is a vote in favor of a minority or fringe candidate, either from the far-left, far-right or self-presenting as a candidate foreign to the political system.
