This workshop will examine recurring themes of campaigning and voting behaviour in 150 years of Canadian federal elections. The success of particular parties and leaders in establishing dominant positions over substantial time periods has been based on a recognizable pattern of emphasis on the same kinds of issues − those involving the economy, national cohesion, and social welfare. On the surface, periods of party/leader dominance seem to be at variance with the observed volatility of individual voting behaviour in Canada. This “puzzle” has been a subject of study for several generations of scholars, leading to conflicting theories of Canadian partisanship and electoral behavior. The 2015 election, which exemplifies many of these seeming contradictions, will be a particular focus. We will also examine the effects of Canadian political institutions on both electoral behaviour and election outcomes over time, and the various assessments of the state of Canadian democracy today.
