What role do presidential candidate character traits play in vote decisions? To some, the answer is obvious as campaigns, journalists, pundits, and voters frequently differentiate presidential candidates in terms of their personal qualities—traits are deemed important. On the other hand, past research suggests that, while candidate character traits are short term forces, they hold relatively limited in influence on vote preference. However, theoretical and methodological limitations may have hindered past research ability to detect the true influence of character traits in voter decisions. This author reviews past literature, offers a clear conceptualization of candidate character traits, presents ways in which trait may influence vote choice, and suggests areas for future research.
