During the 2016 presidential election campaign in the United States, scholars argued that authoritarian visions of the family are associated with support for Donald Trump, a candidate also noted to exhibit authoritarian or illiberal tendencies. Though it is plausible that “authoritarian” citizens (defined by parenting attitudes) vote for “authoritarian” candidates (defined by disrespect for democratic institutions), past research provides relatively little guide regarding this relationship. One reason is that few US candidates announce overtly authoritarian views. Latin America, by contrast, has had many such candidates. We take advantage of this variation using the 2012 AmericasBarometer, which applied a battery of authoritarian parenting attitudes. We first describe mass authoritarianism across Latin America, showing it is associated with many social attitudes. We then examine authoritarians’ voting behavior, distinguishing between support for “ mano dura” (“strong arm”) candidates, who are usually rightists, and for candidates threatening violations of general civil liberties, who are often leftists in Latin America. We find that authoritarians tend to vote for right-wing authoritarian candidates, while authoritarianism boosts support for candidates threatening civil liberty violations only among citizens identifying on the ideological right. Education is the most consistent determinant reducing support for both leftist and rightist authoritarian candidates.
