Greene's Survey Analysis Within the Social Identity Tradition Suggests That

Greene's survey analysis within the social identity tradition suggests that identifying with a political party (categorizing oneself as a Republican or as a Democrat) increases positive attitudes toward that party and individuals' likelihoods of engaging in partisan political behaviors (e.g." campaigning for the party) What's interesting about Greene's findings is that having a partisan political identity affected party attitudes and partisan political behaviors:

A) across the age spectrum
B) among individuals who had party affiliations of the same strength and similar political ideologies
C) by increasing the frequency with which individuals sought out the company of others with similar political views
D) even among survey respondents who were themselves politicians
E) for years after the initial study was conducted
