Protestants are way more conservative and reactionary than Catholics in Latin America thanks to US influence. All the small protestants churches that existed before were repressed by the US backed military dictatorships because they were seen as too liberal (which radicalized them to be more left-wing and united with their left-wing catholic and jewish counterparts during the 1970s).

Usually Catholics are seen as more liberal because the majority of the population are Catholics or have a religion that has strong ties with Catholicism (be Espiritismo or some Native/Afro-Latino Religion). Meanwhile Protestants megachurches promote shit like Zionism, Anti-Communism and Anti-LGBTQ+ stuff. There are small groups inside these Protestants Churches that actually support Left-Wing policies (such as being critical of Israel, supporting LGBTQ+ rights, Native Rights, etc...) and Left-Wing candidates (which you can see in Brazil, Colombia and Venezuela) but they keep the Protestant rhetoric.
