what happens if hispanics begin voting like blacks?

Just a not on protestantism among the Hispanics. One should consider this together with fairly massive conversion to protestantism within Latin America: it's not always part of integration, but, rather, a continuation of what's happening within, say, Mexico.

In Mexico protestant conversion is, mostly, happening among the lower classes, especially among the Natives, especially in the South. Chiapas by now is barely 60% Catholic and in a few other states Catholics are closer to 80%. Of course, the Bajio plateau stays, mostly, Catholic (Guanajuato, for instance, is close to 100%). But even in Mexico City non-Catholics are approaching 10% of the population. There is a lot of conversion to evangelical protestantism, to pentecostalism, etc. And, given that the protestants are both poor and, at least, literate - they have to read the Bible - they are also quite mobile, so I wouldn't be surprized if their proportion among the migrants is, actually, higher.

Hispanics won´t vote like blacks, because, as a group, they are less homogenous. There Mexicans, Puerto Ricans, Dominicans and Cubans, there are new migrants and people whose ancestors haven´t moved for centuries, etc., etc. But a certain further swing of many of these groups away from GOP is still quite likely.
