Purpose To evaluate the accuracy of the populist label applied to former Thai Prime Minister Thaksin Shinawatra by both political opponents and past scholarly observers. Methods We distinguish more colloquial uses of the term that refer to a leader's policies or political strategies and instead turn to an ideational definition of populism. We then use content analysis, an empirical methodology used extensively in cross-national work on populism, to identify populist discourse in Thaksin's speeches across his two terms. Results We find that Thaksin has very low levels of populism in his first, but that this jumps to just below the middle of the scale in his second term. We then compare Thaksin's discourse to various other leaders from around the world. His trajectory is most similar to that of Recep Erdogan of Turkey, and we compare the two leaders to highlight both the similarities and differences in policies, ideology, and authoritarian tendencies in order to emphasize the populist parts of their leadership as a distinct concept. Conclusion Using an ideational approach and a systematic empirical strategy, we are able to divorce our evaluation of Thaksin's populism from normative agendas and colloquial uses, which enables us to better understand Thaksin's leadership tenure.
