Mexican Americans are the least liberal Hispanics: I shown in previous posts that immigrants tilt the country left. In particular, I have focused on Mexicans since they are the largest group. Other Hispanics are often lumped in with Mexicans, but they might very well have different politics. Cuban Americans are known for their Republican voting, for example.
The General Social Survey asked 9,613 people their if they had Hispanic origins, and their political views (ranging from "extremely liberal" (1) to "extremely conservative" (7)). Here are the means subtracted from 7 so that higher scores show greater liberalism:
Mean liberalism score
Puerto Ricans 3.19
Central Americans 3.22
South Americans 3.26
All other Hispanics are worse than Mexicans. Even Cubans are farther to the left. It might be the case that the only reason why they vote Republican is over the issue of Cuba. They fit in with general pattern of liberalism among immigrants. Their numbers are also consistent with the high liberalism scores of other Caribbean people (i.e., Puerto Ricans, Dominicans).
Central and South Americans are also more liberal than Mexicans. According to GSS data, there simply are no conservative Hispanic groups. (The closest thing perhaps is Filipinos).
Hispanics are another example of how Catholicism in America does not move people right. Priests pray for the end of abortion, but parishioners want social programs.
