This article investigates how Canadian voters react to a perceived lack of quality provided by their most preferred parties and how the anticipated election outcome conditions the reactions. The central argument is that a lack of quality motivates voters to signal their discontent by voting insincerely—that is, they cast a protest vote. The effect is expected to be moderated by the anticipated constituency result. The arguments are tested with two-wave panel survey data from the 2015 Canadian federal election, collected by the Making Electoral Democracy Work (MEDW) project. The results support the central argument but remain inconclusive about the expected moderating effects.
