Reply #2: That seems like a natural assumption, but...

...doesn't necessarily hold up. As a Fundamentalist Atheist, I have the same concerns.

To use the biggest and closest Hispanic example to the USA: Mexico has been officially secular since its 1857 constitution. In many ways, it's even more "officially secular" than the USA. In Mexico, the clergy cannot run for political office or endorse candidates.

At least one right-wing idiot found out the hard way that many Hispanics don't like to mix religion and politics. When "B-1" Bob Dornan was trying to take back his Congressional seat from Loretta Sanchez in Orange County, CA, he printed up campaign pamphlets in Spanish. They had the Virgin of Guadalupe on the cover. Inside were gory anti-abortion photos, in full color. There was a huge uproar in the Hispanic community and Dornan dumped those pamphlets. And lost the election.

I've lived in Los Angeles for many years and asked Hispanics about this. From the ones I've talked to (who admittedly fall on the liberal side of things), even religious Hispanics see religion and politics as two separate entities. They may go to Mass every Sunday but will vote their real-world interests first.
