Based on his record as president, Carlos Ibáñez is usually considered a populist caudillo in Chilean historiography. However, there are few studies of whether his electoral base permits this classification or of the type of populism he represented. In his four presidential bids between 1927 and 1952, Ibáñez ran with the support of both left- and right-wing parties. Using municipal-level data, we assess his electoral support in the 1942 and 1952 presidential campaigns and support for Ibañista parties in the 1953 legislative elections. In 1942, Ibáñez's electoral base was similar to that of right-wing candidates while, in 1952, his support increased in areas where the Left was historically strong. While he received consistent support in agricultural areas, it fluctuated in mining and industrial areas.
