A Taxonomy of Protest Voting

In: Annual review of political science, Band 21, Heft 1, S. 135-154

Abstract

Observers of elections often report that voters have engaged in protest voting. We find that "protest voting" refers to a wide range of behaviors, and we create a taxonomy of these phenomena. Support for fringe or insurgent parties is often labeled as protest voting. Voting theorists have used the term in a completely different way, identifying an unusual type of tactical voting as protest voting. Protest voting also occurs when voters cast blank, null, or spoiled ballots. There are also instances when protest voting is organized and directed by political elites. Finally, several countries provide voters with the option of casting a vote for "None of the Above," which some see as a form of protest voting. In addition to developing this taxonomy, we discuss the analytical and empirical challenges confronting research on each type of protest voting.
