We investigated outcomes associated with different types of partisan identity in a sample of political candidates for parliament and local offices (N = 214). We distinguished partisan narcissism, a belief in the greatness of one’s political party that is not appreciated by others, from partisan identification, feeling part of the party and evaluating it positively. We examined their links with self-reported measures of politicians’ functioning in their work: political skill, integrity, and party dedication. Partisan narcissism was associated with lower integrity in one’s political role, meaning those high in partisan narcissism reported more inclination to engage in secrecy, deception, and political blood-sport (behavior also known as politicking). Partisan narcissism did not predict party dedication: it was not associated with intentions to leave the party and volunteering in party activities, and in fact, it was linked to past membership in other political parties. Meanwhile, we found that partisan identification was associated with higher levels of political skill, while also predicting party dedication in that it predicted lower intentions to leave the party and volunteering in party activities but was unrelated to membership in other parties in the past. Cumulatively, these results suggest that partisan identification is associated with competence and dedication in politicians’ work. Conversely, partisan narcissism seems to contribute to being cunning in the political arena and relates to more devious work habits that many find stereotypical of politicians.
