In two studies conducted in Israel (N=1,320), we show that a multi-item Attachment to an Ideological Group (AIG) scale is strongly tied to vote choice and political engagement, and its effects are independent of, and more powerful than, issue-based ideology and partisan identity strength. Compared to individuals with a weak ideological attachment, those who score highly on the AIG scale are more likely to vote for a party from their ideological camp and participate in politics. Moreover, in two survey experiments, respondents high in AIG displayed stronger anger or enthusiasm{\textemdash}known harbingers of political action{\textemdash}in response to threat or reassurance to their ideological group{\textquoteright}s status, attesting to a link between AIG and political engagement. Our findings underscore the importance of ideological group attachments in a volatile multi-party system.\ }, author = {Oshri, Odelia and Yair, Omer and Huddy, Leonie} }
