A large literature argues that public opinion is vulnerable to various typesof framing and cue effects. However, we lack evidence on whether existingfindings, which are typically based on lab experiments involvinglow-salience issues, travel to salient and contentious political issues inreal-world voting situations. We examine the relative importance of issueframes, partisan cues, and their interaction for opinion formation using asurvey experiment conducted around a highly politicized referendum onimmigration policy in Switzerland. We find that voters responded to framesand cues, regardless of their direction, by increasing support for theposition that is in line with their pre-existing partisan attachment. Thisreinforcement effect was most visible among low knowledgeable voters thatidentified with the party that owned the issue. These results support someof the previous findings in the political communication literature, but atthe same time also point toward possible limits to framing effects in thecontext of salient and contested policy issues.
