While support for redistribution remains high across Europe, voting for left-wing parties, traditionally identified with this agenda, has been under par. Past research explains this puzzle by class-based disagreements about redistributive priorities and by second-dimension attitudes. These explanations, however, assume coherent voter preferences reacting to structural changes. By contrast, I argue that part of the puzzle also lies in attitudinal ambivalence—simultaneous negative and positive evaluations—regarding redistributive policy. Using cross-sectional public opinion and party position data, I find that such ambivalence increases with lower political sophistication, greater value conflict, and weaker economic need. Electorally, it deepens detachment between support for redistribution and left-wing self-identification and increases voting for more economically and culturally right-wing parties. These patterns hold independently of class differences and second-dimension attitudes and replicate stably in earlier data. The findings contribute to ongoing debates about attitude structures and voting patterns and illuminate an additional challenge for economically progressive parties.
