All told, there are about 7.8 million Hispanic evangelical Protestants in the United States. They are more likely to be U.S.-born, more likely to speak English, more educated, and wealthier than their Catholic counterparts. They also attend church more often, are more likely to say that their religious beliefs are very important to their politics, and are more likely to vote Republican than Hispanic Catholics.

Most Hispanic evangelicals in the United States have Mexican roots, which isn’t surprising since most Hispanics in the United States have Mexican roots. But while 63 percent of Hispanics traced their origins to Mexico in 2007, only 50 percent of Hispanic evangelicals did. Just 12 percent of Mexican Americans are evangelical Protestants. Among Hispanic evangelicals, those with origins in Central American countries like Guatemala, El Salvador, Honduras, Costa Rica, and Panama have relatively high representation, making up 14 percent of the evangelical population but 9 percent of the total Hispanic population. Twenty-two percent of Central Americans in the United States are evangelicals…

As for party preference, the 2007 Pew poll found 37 percent of evangelical Hispanics identify themselves as Republicans and 32 percent as Democrats. This was the only faith group among Hispanics that preferred the GOP. Going beneath the topline numbers, country of origin also plays a large role in party identification among evangelicals. Fifty-two percent of Puerto Rican evangelicals identify as Democrats and only 18 percent as Republicans, while 19 percent are independents. Among all Hispanics, Puerto Ricans are one of the most Democratic groups (48 percent), trailing only Dominicans (50 percent) in their preference for the Democratic party. Puerto Ricans are also concentrated in the liberal northeastern states of New York and New Jersey, which suggests Puerto Rican affinity for the Democrats may have a regional ingredient. Puerto Ricans are also concentrated in South Florida, where the prominence of the heavily Republican Cuban-American establishment may influence their political affiliation, regardless of religious tradition. 

On the other hand, 47 percent of Mexican evangelicals are Republicans, and only 24 percent are Democrats, with 19 percent identifying as independents, even though only 14 percent of Mexican Catholics and 19 percent of Mexicans in general are Republicans. South American evangelicals, taken as a whole, are split, with 38 percent supporting the GOP, 33 percent supporting the Democrats, and 24 percent identifying as independents.
