This article examines the literature on popular liberalism in nineteenth-century Mexico and the shortcomings of two interpretations: popular liberalism as an alternative to elite liberalism, and popular liberalism as a strategy to ultimately pursue non-liberal ends. It argues that both interpretations tend to overstate the distance between the liberal elite and its popular supporters because of an unexamined, dichotomous conception of liberalism and the people (generally Indigenous and non-Indigenous peasants) as opposites. It draws its examples from studies of local politics and sides with the interpretation of ‘liberalism tout court’ as the best available option to avoid reifications of liberalism and the popular.

This research note contributes updated and extended point estimates of the ideological positions of Brazilian political parties and novel estimates of the positions of all presidents since redemocratization in 1985. Presidents and parties are jointly responsible for the operability of Brazil’s version of coalitional presidentialism. Locating these key political actors in a unidimensional left–right space over time reveals rising challenges to the institutional matrix, particularly since 2013. Ideological polarization among parties has sharply increased, presidents have become more distant from Congress, and the political center has become increasingly vacated. Coalitional presidentialism is being subjected to unprecedented ideological stress as President Luiz Inácio Lula da Silva begins his third term in office.

While invalid voting is often treated as protest behavior in an electoral context, its association with actual political protests has not yet been empirically demonstrated. The relative scarcity of research on the topic is likely due to the hybrid nature of invalid voting as a both formal and informal political gesture. The novel availability of event-based data for public protests in Latin America allows for testing whether their occurrence is connected with changes in spoiled and blank ballots. Using an appropriate dynamic regression model covering variations in the 148 intervals between Latin American legislative elections in the 1979–2021 period, this study finds a strong connection between the emergence of antigovernment protests and surges in invalid voting (and vice versa). This relationship still holds at parity of economic conditions and it is reinforced by a lack of alternation in the party of power. Conversely, the appearance of workers’ strikes appears to work as a substitute for this behavior, which is also chosen by voters when democracy deteriorates, while corruption has no independent impact on invalid voting. Overall this work’s findings promise to send the research agenda on invalid voting in a new direction, previously unexplored because of an absence of fitting data.

Despite the salience of corruption in elections in Latin America and beyond, it remains unclear what makes certain candidates attractive to voters as solutions to address corruption. Building on studies about the effect of candidates’ professional affiliation on voting behavior, we hypothesize that police and military officers are perceived to be more competent to address corruption. We test our theoretical expectations through an online survey of Brazilian voters with an image-based factorial experiment that presents respondents with three randomly generated handbills, varying candidates’ professional affiliations and potential confounders, such as economic policy, insider versus outsider status, and demographic features. Our results demonstrate that candidates affiliated with the police or the military are perceived to be more effective at reducing corruption, all else equal. The effect of police or military professions on candidates’ perceived effectiveness to fight corruption varies according to respondents’ ideology and is particularly significant among conservative voters.
