Objective Previous research has found that southern state legislators demonstrate more progressive ambition than their nonsouthern counterparts. This presents an interesting puzzle with regard to why this difference exists. In this article, we apply the Five‐Factor Model (conscientiousness, agreeableness, neuroticism, openness, and extraversion) to investigate whether regional personality differences exist that can help explain why southern legislators exhibit greater levels of progressive ambition than nonsouthern legislators. Methods Data from a national survey of state legislator are analyzed using ordinal regression. Results Our findings show that higher levels of extraversion and openness among the legislators are directly related to greater levels of political ambition. More specifically, southern legislators appear to possess disproportionately higher levels of extraversion and openness than their nonsouthern counterparts. This helps explain the greater levels of progressive ambition they express. Conclusions In addition to providing insight into progressive ambition, the results reinforce the notion of southern distinctiveness among state legislatures.
