‘A Pioneer in the Struggle for Social Justice’: Manuel Larraín and Transnational Catholic Activism in Latin America in the 1950s and 1960s

This article explores the development of inter-American Catholicism during the 1950s and 1960s. It analyses the role of the Chilean Catholic bishop Manuel Larraín (1900–1966) in his efforts to disseminate his diagnosis of underdevelopment in Latin America and to establish links with the Catholic world in the United States. Based on a review of his writings, the American press and documentation from Catholic organisations, it is suggested that the Chilean bishop advocated the implementation of social reforms and American collaboration to prevent the advance of communism and strengthen Catholicism on the continent.     

Do volatile voters vote less correctly? An analysis of correct voting among vote (intention) switchers in US presidential election campaigns

The literature on electoral volatility and the literature on electoral campaigns hold contradictory views on voters switching vote (intention) during the campaign. In this note, we shed new light on this contradiction, making two contributions. First, we investigate the extent to which stable and volatile voters choose the correct party. Second, we distinguish levels of correct voting and the impact of the act of switching on the correctness of the vote. Our analyses of vote-switching in American elections show that, while volatile voters are less likely to vote correctly, they are more likely to switch from an incorrect to the correct party than vice versa. Furthermore, we show that following the campaign more closely makes voters more likely to switch vote (intention) towards the correct party.
