I think that it is pretty clear that the composition of the Hispanic community (and the rest of the immigrant community as well) has changed since 2000. Many of the older members have died, many younger immigrants have come of age and many more recent immigrants have started to participate in the political process. Poor Romney could not get even a majority of the Cuban vote in Florida. Of course, Romney is very similar to the grotesquely rich elites that have run countries like El Salvador, Venezuela, Argentina and Chile.
They sucked up all the money and resources there were to suck up and caused the unending poverty of these countries.
