Evangelical voters emerge as decisive force in Brazilian elections

The evangelical population in Brazil has grown significantly, rising from 5% in the 1970s to over 30% of the population, representing approximately 50 million people. This demographic shift has translated into substantial political influence, with the evangelical caucus in the Lower House increasing from 17 deputies in 1986 to 210, nearly 40% of the chamber.

Data indicates a strong preference for right-wing candidates among this group. During the first round of elections, Flávio Bolsonaro secured 62% of the intended vote from evangelical followers, compared to 29% for Lula da Silva. Digital engagement further highlights this divide; a study by Casa Galileia and the Instituto Democracia em Xeque found that among the 30 most engaged evangelical political leaders on social media, right-wing figures accounted for 91.3% of interactions, while left-wing leaders represented only 8.7%.

The expansion of these religious movements is partly attributed to their presence in working-class neighborhoods, where they provide spiritual support and community assistance in areas where state services may be lacking.
