Most research on issue ownership examines the topic as an independent variable that may shape campaign strategy or voter behavior. In contrast, our study looks at ownership as a dependent variable. Specifically, we employ a national Internet survey of registered U.S. voters to gauge the extent to which such judgments are influenced by individual‐level factors other than partisan identity. We find that while partisanship shapes ownership beliefs to a considerable degree, policy preferences and performance evaluations have significant effects across a range of valence and position issues. While feelings of ambivalence toward the in‐ or out‐party do not have a consistent effect on ownership beliefs, higher out‐party ambivalence reduces the probability that citizens will identify their own party as owning most issues. It is therefore premature, and probably incorrect, to assume that perceived ownership is little more than an expression of a person's partisan attachment or intended vote.
