Replication Data for: Partisan Messages and Support for Democratic Institutions: Evidence from Survey Experiments in Brazil, Chile, and Colombia

We examine the relationship between partisan social media messages and voters’ support for undemocratic transgressions against the institutions of the President and Congress. Our survey experiments in Brazil, Chile, and Colombia randomly exposed respondents to partisan messages about contentious and consensus issues such as inflation, abortion, crime, and protests. We then assessed whether these messages increased support for undemocratic transgressions. Our findings reveal distinct inter-party differences: opposition voters were more inclined to support presidential impeachment, while incumbent voters were more predisposed to dissolve Congress. However, contrary to our initial pre-registered hypotheses, exposure to partisan social media messages did not consistently augment these tendencies. This implies that while voters often endorse undemocratic measures in line with their partisan leanings, exposure to partisan discourse on social media does not heighten those preferences.
