Is there such a thing as “the Latino voter”?

My father, a Peruvian, was something of a Republican, even when he wasn’t yet a citizen of the United States. For the first 15 years of my parents’ marriage, in Peru, he was mostly concerned with the careening allegiances of his own countrymen: the gaping divide between the elites and the poor; the wild, destabilizing vacillation between right wing and left wing in Latin America; the perpetual pendulum swing between oppression and revolution.
