In a time when freedom of movement is being challenged by an increasing number of European Union member states, and where immigration has been dominating public debate for the past years, this study investigates the effect of media framing (i.e., frame salience and frame sentiment) of migration news on individuals’ attitudes about free movement. Findings indicate that the salience of specific frames (i.e., labor market and security) as well as sentiment, positively influence free movement attitudes of citizens. However, there are country-specific differences. The importance of our findings for our understanding of media effects on policy preferences, as well as for comparative media effects research, are discussed.

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.
