An Anglo-Latino Working Class?

In analyzing Clinton's victory in Pennsylvania, Reihan Salam of the Atlantic.com writes about the existence (or emergence) of an Anglo-Latino working class. He states that for years Latinos were considered as "people of color" who will respond to American politics much as blacks have done. However, Mr. Salam suggests that is not so. Salam suggests the following:

"Suppose the white working class, which is to say the Anglo white working class, is actually expanding to include Latinos of a similar cultural disposition and economic status. Look beyond the color-coded demographic projections and it's at least plausible that a working-class coalition built around an Anglo-Latino bloc will more than hold its own in raw numbers against the emerging Obama coalition of social liberals of all classes, black voters, and reform-minded members of the mass upper middle class. It's also pretty plausible that this Anglo-Latino working class will be more tightly focused on the bread-and-butter issues that Hillary Clinton has emphasized, and less drawn to the somewhat vaguer causes of reinvigorating democracy and expiating this nation's Original Sin that have attracted voters to Obama."
