One key trend changing political environments across advanced industrial democracies is increasing electoral volatility. Despite extensive research, at the individual level we still know relatively little about the mechanisms behind electoral volatility during election campaigns, including the impact of political knowledge. Against this background and based on a four-wave panel study in the context of the 2014 Swedish national election, the purpose of this paper is to investigate (a) patterns of intra-election volatility and the impact of (b) political knowledge on patterns of electoral volatility. Distinguishing between party alienation, crystallization, wavering, reinforcement, and conversion, among other things, findings show some effects from political knowledge on patterns of electoral volatility but only for acquired political knowledge.
